Restoration / 1969 Camaro Front Power Disc / Rear Drum Brake Clips

« on: June 21, 2020, 05:09:23 AM »

I just completed the restoration of the brake clips for my 1969 RS Z/28 Project. My research lead me to a few, incomplete threads on CRG so I thought I would contribute a comprehensive reference thread in case others can benefit from this information in future. All clips shown are original and restored, none are reproduction. All bolts are manganese phosphated and as there are several threads on CRG that discuss where to source phosphating solution and how to convert fasteners I won't address that process.The black chromate fasteners (3 - double hoop style) are first clear (silver) zinc plated followed by a black chromate immersion solution. The result is similar to low-gloss black paint however more durable and it doesn't flake or chip. The finish is also similar to Black Oxide immersion solution (which does not require zinc plating) and both are available from electroplating suppliers like Caswell. For the semi-transparent blue and green clips I used Steel F/X metal solvent dye. Its best to apply it with a low pressure air brush. It dries quickly and produces a fairly durable flat sheen finish. I applied two light coats. I've include a color coded (by clip) reference from the AIM as well as photos I took at MCACN of some original cars with undisturbed clips to show the location and orientation of each clip.

Restoration / Fuel Sending Unit Details - Tape and Sleeve

« on: May 11, 2020, 07:45:21 PM »

For the 3/8" single fuel line on my '69 Z, the pipe terminates at the top of the rear frame rail then connects via a 5" rubber hose to the fuel sending unit. The sending unit's fuel pipe is secured, in part, by the fuel tank strap where there is a pinch point between the tank and strap (see photo and AIM diagram). At this position the sending unit pipe is protected by a rubber sleeve covered by tape (see AIM Parts #5 & #6.). During the disassembly of my project I took photos of the sleeve and what was left of the tape. I assume the tape is a crepe style as was used elsewhere during the assembly process. Does anyone have better information on the tape used on the sleeve?

Restoration / 1969 Z Fuel Line Clips, Hoses and Fasteners

« on: April 06, 2020, 04:43:33 PM »

I'm restoring the original 3/8" fuel line clips and fasteners on my Z/28 project and want to confirm the finishes on them. My originals and most other originals that I've seen are hard to assess due to weathering, accumulation of road debris, undercoating etc. The underside of some of the clips offer clues however for others they're not definitive. The aftermarket kits aren't a good reference either as they use colored phosphates vs dies and incorrect clip stampings. There are some partial threads on this subject on CRG but none that are very complete or usable as a front to back reference. The AIM is helpful but doesn't call out finishes. I haven't addressed the hoses or their clips in this post which I will deal with in a future posting.  I'd appreciate input on the markup of the photo of my originals taken during disassembly. The hardware was removed and placed in order of removal from back to front (left of photo to right)

Restoration / 1969 Hood Striker Assembly Finishes

« on: December 04, 2019, 11:21:35 PM »

I attended MCACN this year and had the pleasure of exploring several restored and original Camaros. Among the restored cars was a Legends certified '69 Z (2B Norwood build) that I noticed had a hood striker assembly that was restored unlike what I've seen on most other cars. The hood striker had the (threaded) adjuster shaft finished as natural steel vs zinc phosphate. All other components of the assembly looked correctly restored to me. Is natural steel the correct finish for the adjuster shaft?

 - Bolts - Manganese (dark) phosphate with captured washers
 - Base - Zinc (medium grey) phosphate
 - Spring - Full Gloss black paint
 - Cup - Zinc phosphate
 - Adjuster shaft - ?

Originality / Power Steering Return Hose Script and Clamps

« on: October 23, 2019, 04:28:23 PM »

Looking for input on the correct Saginaw power steering return hose and clamps used in 1969. I have two examples of period-original hoses. When compared it appears the script on both hoses read "P.S. Return DDD-Y" where, I'm assuming, DDD represents the Julian date and the Y is the year of manufacture. If that assumption is correct the examples below would appear to be dated April 21, 1970 and August 25, 1970. Although not Gen1 hoses I was told the script would be the same for 1969? The power steering box side hose fitting was attached to one of the hoses with a pinch clamp which is correct for Gen2 Camaros for both ends of the return hose. Gen1s used Wittek screw clamps or possibly one Wittek screw clamp and one pinch clamp? Input would be appreciated.

Another example apparently dated August 25, 1970

General Discussion / Joe Perri and GEN4 Restorations.

« on: October 08, 2019, 10:14:06 PM »

As many of you know Joe Perri, a legendary restorer of radiator caps, gas caps and original horns under the business name GEN4 passed away earlier this year. His talent will he missed. I read over on the NCRS Forum that an NCRS Member purchased GEN4 (tooling and inventory) in August and will be carrying on the restoration service. The new owner is Tim Bartsch and his number is 701-240-3750. I don’t have any information on his plans, services or prices other than he is operational at the time of writing. I am not affiliated. Would be interested in learning more about his work.

Originality / 1969 Front Shock Absorber Mounting J-Nuts

« on: September 25, 2019, 05:24:53 PM »

I seem to have misplaced the (4) J-Nuts that clip onto the lower control arms and receive the bolts for the front shocks (...and Rich P doesn't have any!). Are these repops exactly the same as the originals or do they differ?

Restoration / 1969 Brake Line Retainer Clips - Finishes

« on: September 06, 2019, 05:18:43 PM »

I'm working on restoring (if possible) the brake line clips on my 69 Z/28 project and want to see if I can duplicate the original, translucent blue finish often seen on the 3/8" clips (as well as the finishes on the other clips). From threads I've read it seems many have tried however I haven't run across a product or technique that comes really close to the original translucent blue so I'm going wade in. When I disassembled my car I didn't take photos of the translucent blue clip finish which is sometimes preserved and appears on the inside of original clips. If anyone has photos - please post them here. Below are the clips available from Camaro parts vendors. The 3/8" clips appear to be an opaque phosphate blue finish or ? and I haven't previously come across a green clip on the cars I've worked on? For the black open hoop clips I'm interested to know if they are were originally painted (semi-gloss black) or finished with black oxide? Would appreciate your photos and input.

Restoration / D80 Spoiler Trunk Lid Sealing Tape

« on: April 02, 2019, 06:24:36 PM »

Fisher Body applied a sealer tape over the production emblem stud holes on the trunk lid when the D80 spoiler option was installed and the "Camaro by Chevrolet" emblem was relocated to a forward location.  Fisher used a sealer tape with a unique woven pattern that can be seen in the photo from John Hinkley's (John Z) February 69 build Norwood Z/28. The location and size of the tape strip Fisher used can be seen in the second photo. I have been trying to locate a sealing tape with the same or a very similar woven pattern. Does anyone have a source for this type and pattern of sealer tape?

Restoration / 12 Bolt Pinion Yoke Strap Finish

« on: March 28, 2019, 05:21:27 PM »

In the process of restoring my 1969 12 bolt diff I'm unclear if the finish on the yoke straps (that hold the U-joint) were originally natural steel, zinc plated or phosphated? The survivor / original straps I've seen are all dark due to age however not often rusty. They were exposed to road debris and road spray as well as to fluids so I'm looking for some input on what's original?

Restoration / Body Mount Tape - Width

« on: December 24, 2018, 02:40:33 PM »

There are a couple of threads on this subject however no posts confirming the actual width of the original body mount tape used by Fisher Body during the 1969 model year to seal the #3 body mount holes. Aftermarket tape is 1 1/2" wide which seems narrow vs the original. A couple of posts noted the approximate width of the original tape at 2" however I'd appreciate if a Member with an original car could confirm the actual width of the tape used by Fisher?

Restoration / 1969 Z/28 Radiator Core - Source?

« on: July 05, 2018, 12:13:13 AM »

I am trying to locate a new, replacement 3 row, 20 3/4" radiator core for my 1969 Z/28 project with OE style fins that will pass judging. I plan to re-use the original dated Harrison tanks and channels however need a core. I checked Heartbeat City and they have no stock and are back-ordered. I searched CRG threads and didn't come up with much.  Does anyone have a source for an original style Z/28 radiator core?

Originality / Rear Axle Brake Line Clip PN# 3956700

« on: June 03, 2018, 06:56:49 PM »

I'm reassembling the 12 bolt differential from my 1969 2B build Norwood RS/Z and trying to confirm the correct rear cover brake hose clip and fastener. There is a CRG thread on a related topic but it doesn' specifically address the clip ( http://www.camaros.org/forum/index.php?topic=3123.msg20270#msg20270 ). After researching the Rear Axle Brake Line Clip PN 3956700 I can't locate a photo of a similar one to compare with and the typical (HBC) repop is different and doesn't spec a bolt or washer. I'm confident that neither the diff or rear brake line have previously been out of the car or worked on as the car was sidelined in the 70's with just 22K miles and has the tell-tale signs of not being messed with including the original single-crimp rear brake line etc. My brake line clip uses a non-captured washer and non-shouldered bolt (see photos). It also has the presence of blue dye typical of frame located brake line clamps. I would appreciate opinions on originality
