Hello all,

I have a 1957 Chevrolet 3100 pickup.  It currently has an open rear end and I believe the gears are 390 or the same as the sedan.  I am wondering about replacing the center section with a posi unit and was wondering if a 8.5 would work?

Thanks,

Jim W.

I fixed the slight change in width by changing the offset on the wheels I used. In the drag world, the 9 bolt is sometimes considered to be a much superior choice to the 10 bolt. IF you go that route, make sure to get the 11 tooth pinion/ 41 tooth ring if you go for the 3:73:1--it's much stronger than the 10 tooth pinion/37 tooth ring. --Miq On Thu, May 16, 2024 at 11:20=E2=80=AFAM James Wolford = wrote: > Hello all, > > I have a 1957 Chevrolet 3100 pickup.
