1  Camaro Research Group Discussion / General Discussion / Re: GM Lug Nuts on: October 19, 2014, 10:14:50 AM
GM used half a MILLION lug nuts every single day, from MANY vendors; it would be difficult to say that any vendor was exclusive to any given plant at any given time. The multiple-spindle nutrunners that installed the lug nuts didn't mark the nuts in any way - any marking or surface texture on the nut came from the manufacturer.

Looks like there is no pattern for usage between the two different types of fasteners.

John Z. - were the tail lamp housings already assembled from the supplier? If a vendor provides them, who actually would specify the type of fastener head to use?

Thank You,

The taillights were supplied fully-assembled, ready to install, by Guide Lamp Division, and nobody specified the fastener headmarks - fasteners were specified by part number on the lamp drawing. The fastener part number specified the head type (phillips, hex, etc.), and any vendor that supplied that part number had its own headmark on the screw - NOBODY anywhere in the system paid any attention whatsoever to headmarks - only to part numbers.

Has anyone seen a block stamped with a star? Is there any information as to what it signifies?

Rebuilder's symbol.

I'd guess, based on volume economics, that they were stamped from hot-dip galvanized rolled sheet stock, which then required no further processing or handling.  Smiley

 I also need someone that can rebuild my original Master, and both front 4 piston calipers in BRASS.

White Post sleeves with brass, has done lots of work for me over the last 20 years.  (
6  Camaro Research Group Discussion / Decoding/Numbers / Re: #82 on: October 10, 2014, 11:18:01 AM
While cleaning and repairing my 69, I have come across the #82 on several pieces.  The heater core box(pictured), the inside of the fan/ evap suitcase, on the bottom of the evap, back center of the gauge cluster, and on the air distribution duct. the one on the heater box is red the rest are yellow.
has anyone else seen this pattern? know what it was for? was there an RPO 82? or maybe the X82nd car on the line that day?

That's the final assembly sequence number for that car - assigned in the Chevrolet Body Bank and printed in the upper left box on the Body Broadcast sheet.
7  Camaro Research Group Discussion / Restoration / Re: Proper type of sealant or seal to use ??? on: October 07, 2014, 10:54:17 AM
I am looking for the proper sealant(s) to use in the following area so that water doesn't get where it is not supposed to.......

The bolts that attach the rear bumper brackets to the body. The AIM shows a sealant or cement on the bolts but I don't what it actually is.

The rear side marker light bezel studs where they pass through the quarter panel into the trunk....... The rear sidelights must have been installed at Fisher Body since the install is not shown in the AIM. I have the small gaskets that seal the plastic light housings to the body but it seems like the bezel studs will need something.

And basically anywhere else where a bolt or screw passes through the body where you don't want water to enter.

I have some 3M Strip Caulk. Would that be a good candidate? I haven't used it on anything yet. Can it be formed in a small enough portion to coat the bottom of a bolt head?

I am sure I can come up with something myself but I am trying to do it by the book.


3M "Strip-Calk" is essentially identical to the "dum-dum" sealer originally used on the fasteners you noted.

I finally got the AIR system inactivated.  Checked for a vacuum leak around the carb and couldn't find any.  Car seems to hold an idle now without slowly going down and dying.  One thing I have noticed since I have been doing a lot of work with the air cleaner off is that after the car has idled awhile, though still not anywhere near hot, after I shut the engine off a vapor or mist almost as thick as smoke comes out of the carb throat.  The carb is still cold to the touch when this occurs.  What is causing this? 

Crankcase vapors - if you had the air cleaner and PCV hoses connected, you wouldn't see it.

The original Brake Booster Hose Bracket
Darrell, do you see any GM part number like this stamped on your brake booster hose? I just noticed this one on mine.  My car has never been restored, so if this hose is not the original it was a service replacment many years ago. Anyone know if it is the original or not?

That's not a part number - it's a GM Engineering specification number for rubber hose; describes type of rubber, reinforcing layers, burst/collapse limits, test procedures, etc. Reference to that spec (GM 6188-M) will be found on the booster hose part drawing.
10  Camaro Research Group Discussion / Originality / Re: 1100837 alternator on: September 28, 2014, 09:15:19 AM
Being that my engine was cast on the 22nd and assembled on the 25th of August, wouldn't it be a stretch that the H-25th alternator could make it to my engine that fast?

No. The alternator was installed at Norwood, not at the engine plant.
11  Camaro Research Group Discussion / Restoration / Re: Bolt for front wheel fender mouldings on: September 26, 2014, 11:31:02 AM

I am searching for the bolts that hold the front wheel openings mouldings for my 1969 Camaro. I have the small screws for the back mouldings but the front seem to need bolts. I read somewhere the bolt is Part Number 3853846, AMK products page 103 under GM horns (same bolt that holds the horns onto hood latch).

Is this true or where can I get these bolts? I want the most original possible.



1969 SS Convertible

They use the existing fender outer-to-fender inner bolts - no "extra" or "special" bolts required.
12  Camaro Research Group Discussion / Restoration / Re: AM Radio on: September 26, 2014, 11:21:31 AM
Does the radio have some kind of mounting bracket on the back side that I need as well? Seems like it would have to?

See your Assembly Manual, section U63, sheet A3, item #1, 2 and 3 for the bracket and attaching parts.
13  Model Specific Discussions / Trans-Am Camaros / Re: JL8 / J56 4-wheel disc racing brakes on: September 26, 2014, 10:38:58 AM
I sent John an message about this so we'll see what he has to say. It's a bit funny/ironic that the 461X cylinder heads are more desirable than those without the X and the reverse is true with these caliper castings but I think the 461X heads have better ports (if I remember correctly).

There is some evidence to suggest that an "X" added to a GM casting number indicates the first production pour with a minor pattern or process change at the foundry to let the customer (who machined the casting) know that a minor change has been incorporated in the casting, but I haven't been able to document it. Functionally, it's irrelevant and shouldn't affect the casting's price.

The 461X cylinder head is a different issue - those "X" heads had 10cc larger intake ports than the "non-X" 461's, and were prized by racers in classes where they had to run unmodified (no grinding, no porting) stock heads.
14  Camaro Research Group Discussion / Originality / Re: Sway bar bracket change on: September 25, 2014, 10:48:53 AM
While having difficulty trying to find replacement bushings for my sway bar, I often wondered when the change occurred. Any ideas?

My untouched 02D Norwood '69 (built 2/27) has the "fingers" sway bar bracket.
15  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: September 25, 2014, 10:34:26 AM

I see coolant in the lifter valley in the first photo - did you drain coolant before removing the intake manifold?
