FatTony, I have the same rear axle under my '58 4400 (Thor). The unfortunate thing is the front hubs won't work with the front spindles on the older axles. The good news is the rear axle bolts right in place. I used the Hydrobooster and master cylinder as well, I had to fab up a bracket but that's doable. I would say go for the rear axle, mine turned out to be a 4.88 ratio.

Shop around for tires, I paid $110.00 (US) a piece for the 8R/19.5's on my front end. The rears were more money but not bad at $229.00 each for 225/70R/19.5. they are 10 ply rated.
