I am installing a 12 bolt rear in my 51 half-ton. The truck is torn apart down to the frame. I will be installing a 235 in the stock location so that algle remains stock. I could only estimate the needed differential angle at this point which I may have to do.

Can anyone tell me that they have done this before. If so, what angle did you mount the spring pads on the rear end. I think that I have heard that the nose should be angled 5 degrees up. My thanks to anyone who can help me not reinvent the wheel here.
