James,
FWIW, I have noticed Original Production Line Caps have the 2 ribs inside, not the single rib, also the attaching screws are different.
 I never knew about the rolled verses crimped edge, will have to have a look at my Z28 and re post.

My 06A Norwood RSZ28 has the flattened type.

Didn't the LT-1's have floating wrist pins like the 302's?

I don't recall offhand - I don't deal much with Corvettes built after 1967. :-)

Nope, LT1 was pressed pin

My original RSZ28 grille centre is just the GM Black Plastic, owned the car since 74

I thought all these were dipped black?  All of the 69 ones I cleaned were.

YEP, Just restored a unmolested 02B Van Nuys Z28, and they were black, they had runs and pretty sure they were dipped. The brkt that holds the 2 lines together was natural steel.

What is the correct finish for the upper control arm shaft?

 Known Original survivors are Black, even indications of black paint on the bsgs, but lots of guys make them natural ( cast Blast type colour) 30 % gloss Black is Correct

3/16 blind trailer rivits inserted into the smog rails and rivited. They never move and seal up.
113  Camaro Research Group Discussion / Restoration / Re: Exhaust Hangers on: March 04, 2011, 10:27:54 AM
I had spoken with Gardner. They offer the hangers unplated (natural metal) in their base kit. For an additional sum of money they will
plate the hangers. They called it galvanizing but perhaps they mean silver plating.
Does any one know how the judges at a major meet would evaluate plated hanger brackets when the originals were unplated?

I have installed quite a few first gen Gardner Exhausts, their detailed show hangers are silver zinc plated and very nice. They spend a lot of time making the correct rivits like the GM production line parts. The rubber is corded just like the originals. Unfortunately they are only available with their exhaust systems, they dont sell individual parts.            
 As a note of Interest, be carefull when buying NOS hangers, there was a run of them where the upper holes are stamped into the hanger EXACTLY backwards and will not bolt into the body. I have successfully Tig welded those holes up and redrilled them. I then ground/buffed/sanded them off carefully and shot them with Eastwood Matte Clear so they would not rust.
 ALL the other Repo hangers are not even close IMO.
I dont think judges would take points off for plated hangers, but it probably depends on what class you are being judged in.

 Chick,

Yea, the guy I work for has some great original survivor cars, it is a great source of info, I learn something everytime I look at them.
115  Camaro Research Group Discussion / Restoration / Re: Sway Bar End Links - Correct Finish & Bushings on: March 03, 2011, 03:06:45 PM
John Z is bang on as usual!

The 6,000 mile 67 Corvette has WB2C bolts and the bushings are the small diameter ones the same size as the AMK Bushings B-10243 which show the GM part number # 381957.
 I also looked at his 70 Ram Air 4 Trans Am, 20,000 mile car, TOTALY original, it also has small diameter bushings and the WB bolts have WB only.

I have pulled off 1 of my original WB bolts, and I was surprised to find the bolt shank diameter is .342 ( 11/32") NOT 3/8" as I posted earlier. They do have 5/16 Thread on the top. The HBC bolts are the same diameter, as well as another set I have. I allways thought they were 3/8" but they are not.

The AMK small diameter bushings apprear to be correct at this time, and the hole size is smaller than 3/8 to correspond with original bolts. I also checked some Generic aftermarket link kits and they are 3/8" bolts with the larger diameter type bushings.

 Chick and Jeff - I Hope this helps.

Plain Steel unpainted as noted, at least my NOS ones are.

Jeff -

AMK also has the larger diameter bushings although in their description they show it as a shock bushing -

http://www.amkproducts.com/bulk3.asp?part=B%2D10237

This bushing below is shown as a shock or sway bar end link bushing and the GM part # 381957 is the same part number shown in my 69 AIM Assembly Book-

http://www.amkproducts.com/bulk3.asp?part=B%2D10243

I also have a set of the HBC repos and the bolts are exactly the same as my original 69 bolts, they have a WB head marking and are 3/8 shaft with smaller 5/16 thread at the top.

Can someone check their 68 AIM and see if the part number for the bushings ( 381957) and through bolt ( 8790332) is different from 69?





My 68 AIM shows the bushings to be 381957.  The through bolt is 3790332.  I assume these are both the same and your bolt # was a typo?

Not a typo, but the 8 might be a 3, the ink printing is very hard to read in my aim at that part number, so I am guessing it is a 3.

If you go onto the AMK link it shows the 381957 to be the correct bushing, I ordered some recently from AMK and they are the small diameter bushings same as HBC. Unfortunately I changed my originals back in the 70,s they are long gone so I can not say if they were big or small diameter. The bolts are original though and they are WB head marks.
 I wonder if any one has a KNOWN original car with untouched link kits and they can check the diameter of the bushings?
A friend has a very well known DOCUMENTED unmolested 6,000 original miles- 67 Corvette 427/435HP, I am going to check it out as well as his AIM for that part number. I will re post soon.

119  Camaro Research Group Discussion / Originality / Re: Original long bolts for 1969 L/78 motor mounts on: March 01, 2011, 07:50:25 PM
"The Z28 frame brackets are different heights to compensate for the additional thickness of the antilift bracket, their difference is exactly the thickness of the bracket."

Here is my opinion on the frame stand height difference...

This, I believe, is merely a coincidence, as the retrofit was more than 2/3 of the way through 1969 production.

Why, if the safety stop was taken into consideration when the frame stands were designed, were they not installed until after 9-10 months of production? 

Hi James,

You might very well be correct, never thought about it that way. I have changed lots of engines in first gens in the last 40 years and I have never had trouble getting the engine to sit level, but I guess that is why both engine frame stands are slotted. I probably just assumed the hite difference was because of the antilift bracket, mainly because of this post. I ran a Corvette/Camaro restoration shop for 18 years (1987-2005) and I have only seen these anti lift brackets a few times, last 1 was in a 69 Corvette 350/300hp car.
 It would be interesting to know how many cars originally had them, I wonder if lots of them were removed under the engine mount recall program.
 The mystery continues.

Are all components of the front sway bar end links (bolts, nuts, washers & spacers) supposed to be silver zinc or cad?  I can't tell from my original parts.

Also, does anyone know where to get the correct end link bushings?  My original bushings are slightly taller and a different shape than the generic replacement style bushings.  These look like the correct bushings, but only appear to be available as part of a kit:
http://www.heartbeatcity.com/store/product/19683/Camaro-Sway-bar-end-link-kit--exact--67-68-69/

AMK has them, and they have the same smudge/ink ?  marks as the heartbeat ones. I just got some and they are identical. $4 for 4, you need 8 BTW.
