3691  Camaro Research Group Discussion / Originality / Re: Where are the part #'s ??? on: October 07, 2006, 11:39:21 AM
John is there any possibility that they will ever be released for reproduction?
OR is there any way anyone... besides you could get copies?


I doubt if books of O.D. Sheets will ever be released for reproduction; Fisher Body Division was dismembered and disappeared 21 years ago. There may be a set out there in private hands somewhere, but I've never seen one advertised.

Those are "body" parts, which were installed by Fisher Body before Chevrolet got the painted and trimmed body on their side of the plant - that's why they're not shown in the Chevrolet assembly manual - they weren't installed by Chevrolet. In the plants, Fisher Body used O.D. (Operation Description) sheets to build, paint, and trim the body shell, and they have never been released outside GM for reproduction like the Chevrolet assembly manual. A complete book of O.D. sheets is about eight inches thick.

The "CNR" suffix was a 1970 350/300hp automatic from a full-size passenger car, and the 186 heads had many other applications (including trucks) besides Z/28's. It's probably a passenger car 350 with transplanted 186 heads and a Z/28 intake.

Yup, like that.  Smiley

That's the dealer's internal form that constituted a purchase agreement. Here's a sample dealer order form that they filled out and sent to the Zone Office for processing - the Zone edited the order for errors to ensure everything was compatible (a buildable order) and forwarded it to Central Office in Detroit where it was edited again for any production restrictions and was then forwarded to the plant for scheduling.
3696  Camaro Research Group Discussion / Restoration / Re: Correct locaton of proportionong valve on sub frame on: October 04, 2006, 11:21:00 AM
It's a proportioning valve that progressively limits pressure to the rear drum brakes based on line pressure at the inlet; the round valve under the master cylinder is a metering valve (or "hold-off" valve), which doesn't allow fluid pressure to the front discs until there's 30-40 psi in the line. The distribution block has no valving in it at all - it only activates its internal differential pressure warning switch (which lights the warning lamp in the cluster) when it senses a pressure differential between the front and rear systems.
3697  Camaro Research Group Discussion / Originality / Re: Correct Fan and orientation? on: October 04, 2006, 11:09:15 AM
It's correctly oriented - the blades are always toward the radiator, and the "spider" is always toward the engine.

The door-to-fender fit misalignment with a correctly-aligned D96 pinstripe is very common; the pinstripe was applied at the end of the Final Line, long after the front sheet metal was installed, with a fixture the length of the car that clamped in place and had steel guide rails on it for the Beugler pinstriping guns. Regardless how poor the door-to-fender fit was, the pinstripe would always match from the door to fender.

The "circles" are ejector pin pads, where slides pushed on the casting to eject it from the die-cast mold; they have no functional effect at all.
3700  Camaro Research Group Discussion / General Discussion / Re: 1969 Los Angeles Production Numbers on: October 04, 2006, 10:55:12 AM
Van Nuys produced Camaros. Firebirds, and full-size cars, South Gate produced full-size cars, and Fremont produced mid-size cars and trucks; those plants supplied the west coast regions in order to avoid the freight penalties for shipping cars from the midwest and east to the west coast dealers. Eventually the fixed costs of running those plants and the increasing in-bound freight cost for the parts from the midwest and east exceeded the freight penalty for fully-assembled cars, and Van Nuys and South Gate were closed. Fremont was converted to NUMMI (the GM/Toyota joint venture), and it's the only assembly plant still operating in California. Ford and Chrysler also had California assembly plants in the 60's for the same reason, and they were also closed, for the same reasons.
3701  Camaro Research Group Discussion / Restoration / Re: Correct locaton of proportionong valve on sub frame on: October 03, 2006, 02:35:01 PM
That is not the prop valve.

Why do you say it's not the proportioning valve?
3702  Camaro Research Group Discussion / Restoration / Re: Correct locaton of proportionong valve on sub frame on: October 02, 2006, 10:19:57 AM
Here's the prop valve on my 02D '69 - still has the 37-year-old dealer-applied undercoating on it.  Smiley

This site has been a great help to me and I'm curious how John Z keeps the bottom of his car so nice being an original non-restored car?
Thks again:
Sam

As I posted in that thread, the photo isn't my car; the underside of my car doesn't look anywhere near that good - looks like you'd expect to see under a 37-year-old car. Smiley
3704  Camaro Research Group Discussion / General Discussion / Re: fenders on: September 28, 2006, 05:44:00 PM
No part number, but there's a "run number" (the calendar week of the year the fender was stamped) on the vertical flange directly above the rearmost of the two bolts where the fender attaches to the top of the radiator support.  Smiley

Yup, the Eastern Michigan Camaro Club - hosts the Camaro Superfest show every year (with the Western Michigan Camaro Club):
