1963-1994 Unique-To-Corvette Part

[Joe L.]

As sort of a "lead-in" to another post I'm going to put together when I get around to it, there was one unique-to-Corvette part that was used on the vast majority of Corvettes built between 1963 and 1994. I believe this was the ONLY unique-to-Corvette part that was used over such a long period. Now, I want to emphasize again this is a unique-to-Corvette part and not a part used for non-Corvette applications or a standard item like fasteners and things like valve stem cores.

Does anyone know what it is?

Do you remove it to put fuel in?

I would have to guess.........it's related to the driveline or IRS. Maybe something to do with the trailing arm, rear brakes, or differential.

Let's see, how about the U-joints in the driveshaft or half shafts?

p.s. Are there any prizes for the correct answer?

Ignition shielding.

Not at all. If you mean fuel caps, there was no fuel cap used on Corvettes that spanned the C2-C4 period. In fact, there were numerous caps used over that period. Only the 63-74 caps were unique-to-Corvette pieces and there were at least 6 different part numbers over that period.

Joe, How about a hint.

Rear suspension parts were mostly unique-to-Corvette pieces. However, most changed part numbers at least once over the 63-82 period. Some that were the same over the 63-82 period were trailing arm front bushings, spindle support inner shield, spindle support inner deflector, rear spring outer cushions, and rear spring outer retainers. However, NONE of these parts carried over into the C4 era.

No u-joints used over the 63-94 period were unique-to-Corvette pieces and several part numbers and designs were used for each size over the period.

Ignition shielding was definitely unique-to-Corvette. However, the various pieces did change over the 63-82 period and I can't think of any piece that remained the same over the entire period. In any event, none of this carried over into the C4 era.

Yes Joe, How about a clue. Am I warn if I'm in the headlight mechanism?

Hi Joe,
How about the cam adjustment bolt for the rear wheel alignment?

There was much commonality between C3 headlight mechanisms. However, very little between C2, C3 and C4. In fact, there were no common parts between C3 and C4. The common parts between C2 and C3 were limited to a few parts that were not at all Corvette-unique.

I actually did provide a clue in another fairly recent post I made. You guys need to put your thinking caps on.

The adjusting bolt with cam actually changed between 63-76 and 77-82, although the two are 100% functionally interchangeable. The separate cam was the same for 1963 to 1982, but it did not carry over into the C4 era. Also, I believe there was at least one other non-Corvette application for this cam.

Joe,

Just a guess based on one of your recent postings. Lower rear shock nut.
