Hey AndyMan if u rig up a home brew PLEASE post it... I am currently rolling around in a glorified 2wd with 35's on it. I just haven't ordered a posi-lok yet. I'm just not real big on the vacuum thing.

I'll do it man. What I'm doing will be VERY simmilar to this: Home-Brew Posi-lock
That's on like a Dana 35 or something, but it's the same exact principal. The parts on ours are just bigger.

I want to try a couple other things, but essentially, that's what I'm going with. The posi-lok brand setup thing is real nice, but it's just too much $$'s for me to spend when I can accomplish the same thing for $50-60.
