Was just wondering the major differences in the 70's series b models. For example which ones were cummins powered and which used the lj cab.

Im not super familiar with mack but I have driven them and admire them. I saw an old r model frame in the weeds(old front hubs, no factory front brakes) and was wondering why the frame is wider at the front than the rear. I dont recall seeing another make that does this. Is mack the same width in the rear as other makes and just wider in the front?
