I just read your entire build thread. What a great looking truck. And I appreciated seeing the front axle install. I think so far that is what I am going to do. I have an alignment tool coming that will show me caster and camber.
I was considering a little bit longer spring up front. As long as the ride height is even front to rear is all that matters. I will probably start on the rear first to see what I need to do up front. I have a really neat X model 69 wagoneer that has been sitting for 15 years now. It is getting jealous over this new addition to the jeep family.
