Re: Difference between 55 & 56 rear end assemblies

I need to do some asking around but the Twin Traction carriers should be a standard Dana/Spicer Power loc.
It is still a highly regarded unit, GM basically copied it for the fabled 55-64 Olds/Pontiac rear ends.
The only major change is more axle splines, the more, the better. (to a point)
Guessing that Craig would be an expert on these??
