Trim Ring Question

[Henry S.]

I bought a set of rallys and these trim rings came with them. I know they are not correct for the 67 but does anyone know what they are for. I know most the repo reproductions have clips all the way around. Thanks for any input.
Take care,
Shooter

I can't answer your question on what your ring's original application was; however the service replacement trim rings (Group 5.871, p/n 9796696) has 17 grips around the entire inside diameter. Thus, it is not just repros that employ such designs. This part was discontinued last year, I believe, with the latest GM list at about $270 each! Photo is of this ring from box dated 1979. I'd guess the ring in your picture is aftermarket, unless there was yet another style that was used between '67 & '79.

The original trim rings for 1967 Corvette rally wheels were GM #3901708. These were discontinued in May, 1975 and replaced by the GM #9796696. The latter are the type with the retaining clips all the way around. The 9796696 were originally used for some Pontiac application, but I don't know which one.

I always thought the GM #3901708 used the 4 clip arrangement like the rings for 68-82. However, I don't know that, for sure.

Thanks Joe.
I bought these with a set of 15x7 rallys that were on a 69 or 70 Camaro. I thought with only having 4 clips they would have been from that era. Joe, are the six inch 67 rally trim rings the same as the ones that fit the seven inch 68's?

No, they are not. The 1967 trim rings were unique to that year as far as Corvettes go. The 68 trim rings were the same as 69-82.

Thanks for the information Joe. Since I've never owned a C-3 I'm not that familiar with them, I have a hard enough time with the midyears. Since the trim rings for 68 was the same as 69-82 were the rally wheels for 68 seven or eight inch?

Re: Trim Ring Question

1968 were seven inch, 1969 up were eight inch

Re: Trim Ring Question

Joe is, of course, correct about the 1968 trim ring being the same in appearnce design clear up thru 1982.

The earlier point about the 1967 trim ring being offered under part number 3901708 until being discontinued in May of 1975, comes into play with the later '68 to '82 trim ring. The '67 trim ring was evidentially discontinued due to DOT concerns. In 1975, the four "S" clip attachment design was declared unsafe (could fly off at high speeds).
Although the 1968 design does carry thru to 1982, the clip design changes at the end of the 1975 model year.
In known original examples I have seen ('68 to '82), the four "S" clip attachments are only on trim rings up to 1975. The 1976 thru 1982 trim rings have the later (DOT approved) attachment method.

Re: Trim Ring Question

Ridge does that 1976 to 1982 clip look like what Shooter posted at the beginning of this thread, or is it something else? I don't have a dog in that race, but I am always open to learning something new.

Terry, unfortunately, I can't answer that question with conviction.

In the past I owned a 1968, and 1975 Corvettes that had the four "S" clip attaching system.
My 1981 did not, however.....I can't remember exactly what the clips looked like, only that they were not the four "S" clips.

I've mentioned before that I used to sell original and NOS parts. I've bought and re-sold hundreds of trim rings and center caps. I have seen that type of clip that Shooter posted before, on loose "spare" trim rings, but do not have first-hand knowledge or documentation from known original cars.
My best guess is that was possibly an "interim" clip design in 1976 or so, but this is only a GUESS, at best.
I'm pretty sure my non-aluminum wheel 1981 had the small clip design that goes all the way around the trim ring, as it seen on later service replacments. I wish I had photographed them, as I did not realize I would be afflicted with "CRS" disease at 56 years old.

I better shut up at this point, as I had to apologize about my center cap "gold tone" error just a couple of days ago.......

I only know about 2% of what I need to know about '67s. Better leave it at that.

Re: Trim Ring Question

We (CRG - Camaro Research Group) have documented both trim ring designs on original '69 Camaro Z/28 15x7 "YH" rally wheels; early to mid-'69 production with the four "S"-clip rings, and late production with the gripper fingers all the way around the ring.

John,
The set of rallys I bought (15x7) came with the trim rings and derby caps. I bought them sight unseen through a friend. They were on a 69-70 Camaro but I know they didn't come on the car since 3 were FW wheels and the other one was an AD wheel. Supposedly the guy had the car since mid 70's and hadn't changed anything on the wheels. Can you tell by the clips on the rings I posted if they were from that era either replacements or OE? Since I couldn't find any part numbers on them anywhere did any trim rings come with numbers on them? Thanks John.

Henry -

I don't recognize the type of retainer shown in your photos, but I'm not familiar with the details of '70-up Camaro items; we're focused solely on first-generation ('67-'69) Camaros. The second-generation guys hang out at www.nastyz28.com, and may be able to answer your question.

Thanks again John, I'll check them out.
