I'm looking for guidance in determining what non-posi differential gears/guts will fit in the Oct '56 differential housing I've located for my '57. From earlier postings, the 55-64 complete differentials are interchangable but I assume the inside parts may not all be compatible. As an fyi, I plan to install either 3:55 or 3:70 gears in the carrier.
Thanks
