N66 5 spoke rims.... nice set!

[Mr70]

How deep are those two center caps?
1/8 or 1/4?
Clip on or bolt on?

[DarrenX33]

What is the difference in the depth please? Cause I'd like to go out and measure mine to.

Nice set of wheels Bud.

DarrenX33, the original center caps have a depth of approximately a 1/4" where the emblem is at. Sometime in the early 80's the tooling was starting to wear out and the depth was changed to just under 1/8". This is the one you will find NOS from GM and all parts vendors that still carry the GM part. The new reproduction made by Goodmark has the correct depth and is identical to the original GM part. For some reason the depth on the Oldsmobile Super Stock I rim center cap never changed by GM. The only visual difference between the Chevrolet cap and it is the 3/16" styling ridge around the bottom of the cap where it mates to the wheel................RatPack.....................

Darren
I thought you were waiting for Bud to answer by measuring his,sorry.

"Sometime in the early 80's the tooling was starting to wear out and the depth was changed to just under 1/8".
This is not true.GM changed the depth of the cap to 1/8 around 1973 as a service part.
I & others in the NCOA have documented this.
I have an NOS set in dated GM boxes.Just wanted to add this.

[DarrenX33]

No sweat.

Mr70, I stand corrected. The only reason I thought it might have been the early 80's is that I bought a set in 84 from the local dealer and 3 of them were the shallow style with one being the original depth...........Troy/RatPack.......
