As it says. I have 1 & need a match. Must not have ever been turned (i.e. 9.500 - would consider one very minimally cut).
I think they came on Caprice also.It's been over 20yrs but I'm pretty sure that's what mine are off of. Chris
Finding one that has not been used up, or turned - that's going to be tough. Maybe someone out there has NOS ones. What did they come on? Several vehicles in the very late seventies used them, along with other aluminum body parts. '78-'80 Monte Carlo '78 up BOP examples - to include Grand Nationals already listed Certain "box" Caprices and Impalas with the standard NON Fleet suspension
I just acquired an uncut one & looking for it's match so they are out there, albeit not many I'm sure. Last year I picked up a pair of uncut BBB/Sportwagon aluminum front drums.
I found the match to the one I got from you along w/it! It's w/in .005." Picked up 4 of 'em. That one, the uncut one, and two that are around 9.570 & sold that pair.
