I just got a new axle for my bus. I found a great deal on a Dana 80 with disc brakes, 4.63 gears and came from a 2002 Chevy 3500HD truck with factory 19.5s on it. I had the guy measure the width of the outside to outside tires and it was about an inch wider than mine, although it could be just the difference in tire size. I'll have to get the measurements for WMS to WMS on it and compare to mine. I did measure the spring moubnts and oddly enough, or not, they are the same at 40.5". This is looking like a good swap so far. I'm probably going to wait until Spring to do the actual swap though and also do front spindle swaps for disc brakes like in Grigg's Tech Tip. Also change the transmission to a TH400. Lots of work to do.
