The only difference besides motor mounts is the single stud idler arm. 6 cylinder bars will have the most stored energy to help pitch rotate. Use offset upper control arm bushings from Moog to gain caster. I shortened my strut rods 3/8" by cutting off the ends. Then turned them down in a lathe. Slid .090"×.750" Moly tubing over the ends then welded. This gained caster as well. The outer tie rods are replaced with custom fabbed tie rod sleeves, Speedway tapered studs, and heim joints. This was done to obtain zero toe throughout front travel. To be honest it wasn't to bad to start with. Along with good shocks will do it. Cut the K-frame to get at the pan easier. Mine regularly runs 145+, sons runs 138+
