Originality / Re: PF25 or 29 oil filter for 68
« on: April 23, 2020, 04:10:34 PM »Chick you are correct about the PF 29 and FWIW PF29's come up occasionally on EBAY.
The NCRS has still not come around on the black AC logo on the oil filter...
They acknowledge the 1100 mile 1970 Camaro Z28 charlie had and it's oil filter however they do not accept anything other than the white filter with the blue and red AC logo for full points in judging.
Interesting. There is a larger body of evidence from other ultra low mileage cars and filter take-offs to support the use of the black on white assembly line PF oil filters.

Restoration / Re: 1969 Z Fuel Line Clips, Hoses and Fasteners
« on: April 13, 2020, 06:13:15 PM »Here's my attempt at replicating original fuel and brake line clip finishes:Although not a fuel line clip, from my limited research I believe the only green/olive brake clip used on a Z/28 is the the 5/16" clip, PN# 3952718 shown in the photo from R68GTO (red circled). The other, smaller (3/16") clips shown nearby, PN# 3953272 I believe are clear zinc / silver cad. The 5/16" clip is larger so it can clamp the protective wire sheathing also as shown in the photo. This can be seen in the AIM Pg 63, Sheet 5, UPC B1 The exception may be the clip used on the differential cover (right side) as shown in Post #11 which varies between 2 styles and 3 finishes and is usually natural.
Brake line clip - Testers Olive Green aerosol
Fuel line clips - more experimentation on this one.....let me know which you think looks the most like the originals
5/16" clip, PN# 3952718

Thanks for your input, I'm hoping the product of this thread will be a clear and future reference for which finishes belong to which clips.

« on: April 06, 2020, 07:19:50 PM »Unless it will physically chip off the clips they were PROBABLY not semi gloss paint, they are in all likely hood black passivation of ZINC (which would offer MUCH more corrosion resistance than black semigloss paint (the fuel block "Y" is also black passivation of ZINC). The reason I say this is the Olive clips were not painted they were OLIVE passivation of ZINC - which is the toughest ZINC passivation. Black fuel line and olive fuel line clamps that I have tested do not "chip"
Olive is toughest with Black being the next toughest.
With the blue dye, I AM SURE it was over ZINC plating.
Thanks James. You refer to "olive clips", which one(s) are you saying receive that finish?

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 / Re: Getting the correct bell housing finish ???
« on: April 03, 2020, 01:57:35 AM »Hate to hijack, but in Lloyd's picture, the upper bellhousing has a boss with a hole on the passenger side upper corner, while the lower one does not. Seems to mirror the boss on the driver's side in Dave's pictures at the beginning of this thread. Why the difference, and which one would be correct for the '69 model year?
There is another post on the Yenko site about 403 bellhousing differences I have been involved in under-
“Technical & Restoration”
FWIW I have found 403 bellhousings with the mold numbers 1-9, and some have the extra boss and some don’t. It seems like on known original cars that late 69, early 70 the rh boss is more frequent.
Lloyd , which bellhousing is out of your car and can you please post pictures of both bellhousing cast part number areas including the status markers and mold number 1-9. I’ll add them onto my bellhousing list. Thanks.
Mike.
Happy to post photos Mike, my original 403 is at my shop (that photo is about 2 years old) and the other bellhousing on the stack is from a 68Z, don't recall which is which. I'll post photos in the next couple of days.

"Do you use anything on them afterwards to preserve the finish?"
Dave, for aluminium its not necessary to apply a protective finish or coating after vapor blasting as its not prone to short term oxidation. When vapor blasting steel and alloys I use RPM or Boeshield as they do tend to flash rust if not treated shortly after blasting.
