the later axles are good for later gm swaps, the 79 kp style is perfect for rangers.
just build some offset hanger brackets to run some gm leaf springs and a histeer arm on the passenger side and you can use the stock long side steering link to steer it initially.
if you like it, buy all the nice shit to build a trac bar and heavy duty steering.
the dana 60 is overkill for the vast majority of ranger abusers, but i love it... i still break shit though and it is really expensive to replace normal wear parts.
it is heavy and noticeable compared directly to a dana 35 tb, but at my ride height its welcome for cog. combine that with full width and the handling is quite acceptable with 37 in tires on the hi-way and the 2 lane twisties.
