Well, my hopes are, with my 4 speed actually being a 3 speed with a granny low, that will just become my first gear. Then see how it goes from there. Problem is, the SM465 doesn't synchro the granny gear, so that might be a bit of a pain.
Worse comes to worse i have convinced myself that I will learn to regear it on my own. Maybe buy another 10 bolt axle and regear it off the truck and swap them when I'm done. Then, after I know what I'm doing, do the front. We'll see. I also want a rear locker, but they make ones (like Lockrite and Spartan) that just drop in where the spider gears are, so you dont have to futz around with the ring and pinion.
