Re: Help with Rear Axle
Before you spend any money on the new axle assembly, make sure overall width is the same as what you have. Then, as suggested above, your best bet may be to install your existing internals components in the new housing.
If the ring and pinion gears in the new axle look OK, you may be able to sell them. Unless severely abused, 12-bolt truck gears will last 100s of thousands of miles. When I added a posi unit to my 69 C10's 12-bolt, the original gears still had proper backlash and looked like new. I replaced the carrier and pinion bearings, but probably didn't need to.
BTW, a posi looks something like this, and uses clutches or cones instead of spider gears.
