I am not sure ...I am on vacation I think 265 60 15....8" wheel from summit racing.
THEY DO NOT JUST FIT ON!!!! they rub the leaf spring. I don't want to mini tub this car.
The off set shackles will work....not really that cheep.
3" studs with a spacer will work

Or a cheep b body 8 3/4 rear end will work...

I will check when I get home....as long as I don't have any problems with this east coast storms

Ok I would appreciate you checking on that for me. And if you could when you find out could you please PM me.
