Re: mid year wheels

Re: mid year wheels
That wheel was a service replacement and has no correct "application" on a Corvette. I've heard they were riveted originally, but all I've ever seen were riveted.
They will fit the rear hubs on a solid axle car but you will need to grind out the center holes to fit the front. They also fit a 63 and 64 but you will ruin your wheelcovers trying to install them on them. If you like dog dish hub caps, they fit fine.

Re: mid year wheels
the wheels do not have the bumps on them to hold the dog dish hub caps ? so i am still confused .. i found this page in my gm parts book it also calls for the wheel to be riveted look below thanks Don..Comment

Re: mid year wheels
Don,
I assume the auction you mentioned is at this link. These wheels have the 3 nubs around the center section to retain a dog dish cap.
If the second set he has doesn't have the nubs, they are likely the 65/66 service replacement style. I don't recall that part number, but it isn't the 8080.

Donald,
Can you post a picture or info where we can see them. I believe I have 8080 wheels on my 63 and they are riveted and have the extra step inside to clear the 65-66 disc calipers so they can be used for 63-66 corvette. These wheels do not have the bumps for the small hub caps either.
If it was not for the fact they are riveted I think they would pass for 65-66 wheels all day long. I can't tell a difference.

Re: mid year wheels
Don -- the first appearance of the '8080's in my P&A30 books is in the Oct '66 (1967) edition; they're called out for '57-64 Corvette and '62-3 Police. Mind you, the stock '65-6 steel wheels # 3869156 were still available. As Tim says, they clear the calipers if used on '65-up C2's.
May want to check w/Lawrence @ Western; I seem to remember a set of five '8080's with stickers -- I cleaned him out of his last two factory '65-6 rims

Re: mid year wheels
Don,
At first blush you would think these wheels would clear the calipers, but I know a person who mounted tires and bolted a set onto his 66. He let the car off jacks and drove away with a hideous grinding noise coming from the front wheels. He didn't make it out of his driveway before he realized what the problem was.
I watched a real set of 65/6 wheels sell recently for $400 on eBay a couple of weeks ago. Don't waste your money on 8080 wheels.

Re: mid year wheels
I agree. I don't think the 8080 wheels were ever used on any Corvette. The original 63 and 64 part numbers were discontinued and replaced with the 8080, as I remember.
I also seem to remember that the offset was different than original wheels even though the numbers shown in the parts book show they are correct.
I never had a problem getting the 63 hubcaps on these wheels.
The 8080 is obviously incorrect/non original when viewed from the back side, even if installed on the car. The original 63 wheel was shaped much different than the 8080. I think Wayne has a great pic of both the 63-64 and 65 and later wheels that show this difference?Comment

Re: mid year wheels
Now I am confused, I have 5 1/2" wheels with no nubs and look identical to 65-66 wheels inside except rivets. I have not checked offset but I will and report back. Could these be 3869156 replacement wheels? My 1972 GM parts book says that # is welded but I am starting to think the book may have errors.
Batteries dead on camera but I will post a picture later.
Someone is going to be very dissapointed in there ebay purchase!!Comment

Re: mid year wheels
Michael -- I think that '64 comparison pic (annotated, even !) came from Tracy C. I don't even have any C2 drum brake 15 x 5_12_K's.
My contribution to rolling hardware was a comparison shot of '65-6 steel wheels [rims side-by-side] with '66 KO's, showing that (with KO adapter in place) the inboard rim edge was the same, and all the extra width was shifted to the outboard.
Found a stick-it note in one of my P&A catalogs showing the '65-6 steel wheel # 3869156 was still pricing out, $155 in May of 1992, at a Chev dealer in Montreal. (was too expensive for me back then). Also list price was $59 in May 1980 GM Canada Master Price Book. The 3838080 shows at $38 in same source. Maybe Joe L. can tell us when the '156' finally died.
So I'm with you that the '8080' was (probably) NEVER listed by GM as a replacement for disc brake '65-6's.Comment

Re: mid year wheels
Thanks Wayne. I think your right, it may have been either Tracy Crisler or Bob Jorjorian. (kinda looks like Jorjorian's driveway though) I saved the pic that he posted about a year ago that clearly shows the difference between 63-64 and 65 and later wheels. (posted below) The deep angle of the inside of a 63-64 would certainly interfer with the brake caliper of a 65.
I know the "service only" 8080 wheel didn't look like the original 63-64 wheels in this area. It was shaped like a 65 and later 3869156. I'm not sure if that change was strictly for caliper clearance though.
The old 64 and earlier design did present some safety issues and that, supposedly, was why that design was scrapped.
I also remember other discussions here that described some of the 3869156 wheels for 65-66 as being riveted instead of welded.
The 63-64 wheel on the right.Comment
