Hey guys, I am thinking about getting a new rear end for my 71' Riviera. It seems like by the time a guy was done finding and refreshing a a used unit, it wouldn't be THAT much less than a new one. I don't see anything set up for an E body Buick, but I could order it bare and weld on my own spring perches. Strange has some good sales going on and I was wondering if anyone had gone this route? I was thinking the S60 with a helical gear locker. I have a motor being built that should be in the 550hp range, and it is a heavy car... I welded a full size BOP 12 bolt (ring gear bolts) in preparation for the motor, but have heard horror stories about "Lincoln lockers" Any suggestions? Thanks!
