Got a 8.5 10 bolt 3:55 safe-t-track (posi) from a 68 Pontiac GTO.It is complete from drum to drum.

Any problem installing in my 71 Chevelle replacing the original 8.25 10 bolt 3:08 peg leg. 71 also has T400 auto.

Couldn't find a 12 bolt posi for a reasonable price (budget)

Any information or comments would be appreciated

Thanks,

71 malibu (ss clone)

It should bolt right in.
