Looking for one (1) uncut (or very close) aluminum front drum from a BBB for a '70 GS - I assume '69 is the same but not sure if any other years.
I'm pretty sure they are all the same including if they came off a Sportwagon or Vistacruiser. Can check what I have later next week if you haven't found one by then.
I'd bought a pair for the 350 4-sp. car awhile back - One is slightly (a few thou) over & the other slightly under but of course would need to be turned. They looked thick when I bought 'em but didn't have calipers w/me). They'd probably be OK but then I picked up one that appears to have never been turned and I'd sure like to find it's twin.
I am pretty sure the pair on the front of my GS400 are at the limit or slightly over... Let me know if you find a secret cache of these!
