Hi George,

  Thanks for the input. That is good to know and I see it extends into 69!
Question, will you be finishing the outside main body...cast or black?

Thanks again,

 Aside from quarters which have more involved contours and bends, have you used any of these brand door skins? I'm looking to replace a skin and being it's basically a flat surface with miniman bends I would hope the repos would fit nice.

Hi Scott,

  I have the solutions for gray parkerizing. I soda blasted the part on the outside and it cleaned up really nice. I'll parkerize it to restore it to its original finish. The main body I may paint black or leave it and cover it with RPM. My guess is the cast parts may or may not have been painted. I wish I could look back 45 years to see for sure. So much for the repos as they can be misleading in what is supposed to be correct.

 Did you remove the retention screw from the floor on the inside?
860  Camaro Research Group Discussion / Restoration / 67 Hold Off valve finish on: September 06, 2012, 07:20:04 PM
  I received the rebuild kit posted here last week from Muscle Car Research and upon cleaning the original hold off valve parts I noticed the round cover finish looks to be a gray phosphate type of finish. When dry it looks like the gray finish on my 45 ACP. In the images below you can see the interior gray finish as well as its extension into the flat machined edge. On the exterior you can clearly see the remaining gray finish in the machine mark rings. This leads me to believe the cover did in fact have a gray phosphate finish, at least in 67. I see many repro hold-offs and the cover cap is a gold cadmium color. Maybe that was later in 68-69 but this doesn't seem the case for '67. I have researched the CRG archives but can not find a definitive answer as to what the finish should be though I have seen another thread where another person with an early 68 Z had the same interior finish. Many say it was a bright zinc to gold finish. I'll be bringing pictures to shows in case the judging questions it.
  Any other 67 or early 68 owners see the same on your hold-offs? If you haven't opened yours up yet, you  may want to do it. It is a surprise of the amount of brown crud that develops inside though the outside looks clean.
Thanks to Muscle Car Research LLC for the fast delivery and excellent price!

Thank you,

Let's see:

1-Wrong air cleaner housing
2- I don't see a PVC valve on the left side
3- Shouldn't the tac be a 6K RPM red line for the 396/375HP
4- Steering wheel vs. 760-Z standard interior
5- Wrong pitch on the rear atnenna
6- radiator overflow hose routing
7- A 396/375 with an auto tranny?
8- hood pins
9- engine lift brackets
10- left vave cover rear doesn't look correct
11- wrong radiator cap
12- ash tray front doesn't look correct?
13- front and rear spoliers- well..not factory least there is no fan sticker.

 I placed my order plus the differential valve kit.
I was surprised how good the unit looks from the outside and the amount of brown crud on the inside.
Based on that I'm going to rebuild the brake pressure differential valve because I'm sure that has crud too.
The rest of my brake components are either new or rebuilt.

Thank you for the very well prepared instructions too!

863  Camaro Research Group Discussion / Restoration / Re: GM 3905525 Metering Valve Disassembly and Rebuild on: September 01, 2012, 05:06:19 PM
 Perfect timing...
I am looking at mine and could not figure out how to extract the internals until I had seen your article.
As for a classified section, CRG has none specifically but if you post the info here I believe it will spread quickly as many here have the same setup and likely ageing conditions.
I'm certainly interested in what you have.

864  Camaro Research Group Discussion / Restoration / Re: 67 rear fuel line bracket finish? on: August 31, 2012, 07:54:49 PM
 I'm answering my own questions  Grin

  I removed the survivor clip from the car and examined it under a strong magnifying glass after cleaning it with soap and water and it has a slight gray hue to it (definitely a dried out phosphate look) and I gave it the finger nail test.
Painted surfaces, even slightly oxidized, still feel smooth to the nail but the phosphate surface has more granular feeling to it. Kind of like the feel of dragging your nails across a black board.
I'm going with phosphate finish because I have no doubt that is it.

865  Camaro Research Group Discussion / Maintenance / Re: Miss in engine on: August 31, 2012, 03:06:05 PM
 My vote would be rust particles in the lifter that are trapped.
If that much water damage was done to the motor then it's only a matter of time before something else happens.
I would suspect the bearing surfaces (rod and mains) were damaged and will cause troubles soon.
I wonder what the cylinder walls looked like before you had started it again.

866  Camaro Research Group Discussion / Restoration / 67 rear fuel line bracket finish? on: August 29, 2012, 07:56:00 PM
 I searched the CRG archives (and also did a web search) and can't find the answer.
Is the rear fuel line bracket that bolts to the frame and has a square opening for the end of the line to go through painted or phosphate? I looked at my other survivor but it is lightly oxidized and I can't tell for sure if it's paint or phosphate.
The 1967 AIM P/N is 3912538 as shown on UPC 8/B3 item #9.

Thanks in advance,

QUESTION to the experts.

Starting position:
Car build period was:
01 = January, 1967, the month car was built.
D = Fourth week of the month.
That means dates between: Monday 01-23-67 to Sunday 01-29-67 correct?

What date was exactly stamped on my original 67 transmission for my car?

  That date is when the build period started. Figure a few days afterwards it was completed providing it didn't get pulled to the side for anything out of the norm. I haven't looked at the Julian date calculator to see if your day dates are accurate. As an example of a 'period' my 67 has a 4B date on the trim tag and the UOIT shows a date of April 13th. Almost at the end of that period.
   But, don't get hung up on the tranny date stamp. The date stamped could have been several weeks before the car build date and sat in inventory before being used. The fact that it will not be the original tranny will not make any "P" date any more valuable unless you happen to find the real case with the VIN stamped in it. Most cars today do not have their original trannys so it will not impact the value of the car much at all if you plan on selling it later.
  Don't worry about the tranny and just enjoy the car while you have your health and some $$$$ in your pocket. Life is short!

 Welcome Andre'

  Does the partial engine VIN match the hidden VIN? Look below the windshield area under the cowl vent panel closely for the stamped hidden VIN.
What is the block casting date? Can you post pictues of the engine pad?

869  Camaro Research Group Discussion / General Discussion / Re: Modified trim tag on: August 21, 2012, 01:34:42 PM
 There must be a new breed of buyers who may find re-stamped (and possibly re-tagged) acceptable. Thatís cool if that makes them happy and I personally have no gripes with that if it was disclosed up front in earnest. Reading this link below makes it sound more like reality.

 Just to be clear, when you guys say 3/8-16 I assume you mean the shaft is 3/8" thick? I checked mine and verified I did need a 9/16th socket to remove my original bolt as show above.
I posted mine as 9/16-16. I'm not up on the correct syntax for bolt identifications.
