'68 Trim Rings

[Charles P.]

I'm trying to locate a set of correct trim rings for my '68. The Judging Guide says that with the '68 rim being 7" and the '69 rims being 8", the ring will be closer to the rim on the '68. It says that the wrong depth wheel or wrong depth trim ring can be noted by the distance between the trim ring and the web of the wheel. Sooo, isn't that saying that the trim rings for '68 and '69 are different? If so, does anyone know what the correct distance between rim and ring should be. i have the correct AG code rims on my '68. With the prices for a set of NOS or re-conditioned rings, I want to make sure I get the right set. Any help would be greatly appreciated.

Thanks!
Charles

68 & 69 are the same trim rings

This is my feeling as well. When I bought my '68, it had 8" ralleys. I chenged to the proper "AG" wheels, and everything checked out O.K. I personally feel thet the gap between the trim rings and the wheel centers on the later C3's looks awkward.

Charles,

To add to what Ralph said, '68 original trim rings will have 4 clips to anchor to the rim. The clips will be evenly spaced starting at the valve stem hole being 12, then at the 3, 6 and 9 position around the trim ring. If they are not positioned this way they are not '68's.

That same indexing would be correct for 69 thru 72 as well. Be careful for trim rings with altered crimps to make the indexing correct.

Re: '68 Trim Rings

Thanks guys! I revisited this old mom and pop service station that I remembered when i was a kid. They had literally hundreds of hub caps and rings and wheel dressings of all kinds. When I got there, to my surprise an old man was sitting out front. Well, it was the owner and he still has hundreds of hub caps and rings but they're all pilled up inside in the back of the station. I know I counted a couple of dozen trim rings of differnet sizes, some for 14", some for 15" and most had the four clips. Some are deeper than others which would put the edge closer to the rim like the Judging Guide referred to. I was wondering just how close is close? The aftermarkets I have now are about 3/4" of an inch away from the web of the rim. Terry, with your car being Top Flight, How close is the edge of the ring to the rim?

Thanks!

I have the '68 7" AG wheels with original correct trim rings on my 1965 and the trim ring is close to the wheel center section, approximately 3/16".

Re: '68 Trim Rings

I still have the original wheels on my 1968. The original trim rings and centers were stolen in Dallas about 1974. A acquaintance with a new 1974 Corvette sold me his 74's trim rings and centers since he installed aftermarket wheels. Still have the 74's trim rings and centers on my 68. The clips are at the valve stem location and the other three positions as mentioned in previous posts. Putting a ruler directly from the edge of the trim ring to the steel wheel I measured about 1/4 inch.

My 70's trim rings and centers were stolen in Dallas before the 68's, actually OCT or NOV in 1970. GM replacements have the clips at the valve stems and other correct locations. The distance from the inside edge of the trim ring to the steel wheel is about an inch.

Re: '68 Trim Rings

Thanks again guys!!! Jim and Ray, thanks for taking the time to check your cars for me. I plan to go back to the old service station I mentioned and dig through his pile and I needed something to go by. If I find more than one set I will post them with photos in case someone else is looking for some. Thanks again everyone and have a blessed day!!!

Re: '68 Trim Rings

Hi Charles,

Regarding the measurement question, on mine, the center edge of the trim ring to the center of the rim is just less than .5 inch. Let me know if you need anything else. I'm happy to help.

Trim rings are the same, wheel offset and width are different.
