Re: Difference between 55 & 56 rear end assemblies

When I bought my '55 Patrician someone had already installed a '56 (Aluminium Case) Twin Ultramatic and Twin Traction rear end under it. So far both are working great (or were when I started my rust removal and repaint project about a year ago).

I checked it out in low gear in the parking lot of the tire store when I bought my last set of tires. Laid two perfectly matching strips of rubber for about 250 feet.

The store manager (who didn't believe it had Twin Traction) was impressed.
