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.

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.

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.

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

This URL shows their hot process, it's pricey though

I spent two days with Mike and his crew at Eaton-Detroit Spring when I wrote this feature article on how they manufacture and/or re-arch leaf springs when I was the Technical Editor of "Corvette Enthusiast" magazine; it takes you through their process from start to finish.  :-)

All wheels were received in oiled raw steel, by the thousands, in rail cars. They were cleaned, phosphated, dip-primed black, baked, then the outer face of the wheel was sprayed with either black or body-color wheel enamel and baked again.
The N66's did they go through the process again for the second color?

I believe the short-lived N66 wheels were an exception; there was no way to paint the second color in the plant, so they were received painted. The wheel paint conveyor was a single, long continuous loop of overhead conveyor that went from the wheel receiving area downstairs adjacent to the rail dock to the Bonderite/phosphate system and bake oven upstairs to the flow-coat black primer system and bake oven to the topcoat spray booth to the bake oven and back downstairs to the wheel & tire mounting area for drop-off, and then to the wheel receiving/loading area to pick up more wheels for another cycle.

What was the color of the door stricker on a 1969 Camaro? Was it the simple Zinc steel color or painted? I saw NOS black ones on ebay....

Mines have to be changed because the sleeve is loose.


The striker was received zinc-plated, then it got body color (it was installed in the Body Shop, prior to Paint).

Here's the original dipstick from my untouched 02D '69 Z/28.

Plugs AC43

43's are WAY too cold for normal street use, and will result in some degree of fouling; use 45's (or some other brand that crosses to the 45 heat range).
25  Camaro Research Group Discussion / Restoration / Re: Bolt ID, 67. on: September 15, 2014, 09:44:59 AM
I've never seen the bolts in the bottom photo (3/8" thread size, 9/16" hex head, no washer face, black phosphate) used ANYWHERE on a 1st-Gen Camaro; they look like hardware store lag bolts that have been plated black.
26  Camaro Research Group Discussion / Originality / Re: 1968 z/28 373 rear end inspection marks on: September 15, 2014, 09:30:48 AM
The rears were painted black by eaton. 

Actually, the rear axle was painted at the Chevrolet-Detroit Gear & Axle plant, where it was built; Eaton only supplied the Posi unit.

That's a good question, I approached it last year with no luck. Was looking for the GPM on a stock/replacement pump.

You won't find a GPM rating chart - the number on the pump is primarily for the pump configuration, essentially the bottom half; where are the inlet and outlet, which way do they point, are they clamped or threaded joints, etc. Shop Manual calls for the same volume for the same time for all pumps.

Rather than type it out, I'm attaching Lars Grimsrud's excellent paper on how to install a Chevy V-8 distributor; follow the instructions and you'll have it running in no time.
29  Camaro Research Group Discussion / Maintenance / Re: sway bar bushing replacement on: September 13, 2014, 01:12:53 PM
<<  am in the midst of replacing my sway bar to frame bushings on my 69 , but no matter how I install them, it just doesn't look right
I have the later year mounts(with fingers).
any pointers? does the narrower slip under the top? is it supposed to just squish, leaving an oval for the bar to sit in? do I need to cut something?
Thank you for the help >>

You install the bushing around the sway bar, install the bracket first with extra-long bolts and the bar ends connected with the link bolts to the lower control arms, then replace the extra-long bolts one at a time with the correct shorter bolts. The plant used a compression fixture on the brackets so they could use the shorter bolts.
30  Camaro Research Group Discussion / General Discussion / Re: 1969 Camaro backfiring on: September 13, 2014, 12:46:17 PM
What would cause my 69 Camaro to backfire? First time it happened when I was starting the car and today it happened when I was accelerating on the highway.

Through the carburetor or the exhaust?
