Dave, I'm using a 327 cu inch eng and a turbo 350 in my '51. I was really hoping the rear end out of that 87 Firebird was posi. With the rear end off the ground I turned the third member yoke and both drums turned the same direction, I thought it was a posi. I will not have time to pull the cover until next week. I want to thank all you guys for helping me with this. I know nothing about rear ends.
