  1. I need an axle shaft for a B-83 mack, its the heavey duty or SX model, about a 1963, I am not sure about the year but it has the big block 250 cumins in it and I think they may have come out in 1963. It is 2 and 3/8 inch dia. flat ends Lenth is 39+inches, its broke so not exact probably 39and1/2 17 splines, 3/16 flat top splines 1/4 inch between splines Floating axle- splines on both ends. Thanks
  2. A 5 and 4 is a 5 speed trans with a 4 speed trans behind it, with a short drive line between them, a guad box is a 5 speed with a 4 speed atached behind it, it is called married boxes. The quadroplex is much faster shifting and has about 250 rpm split between every gear,except you do not use the deep under ( first in the brownie ) except in bad spots to start out. and it is much the same with the 5 and 4s except the progressive styles The 5 and 4 fullers and spicers are also good trans but they do not have the same rpm split in every gear and it is to no purpose to catch every gear, for instance 3rd over is so close to 4th under (or low split) it is hard to make that shift so to keep from just wasting time most drivers go from 4th under to 3rd direct hope that helped
