I was wondering if you or anyone could help me when it comes to dom. I need to know if it would be good to use .120 wall or .250 wall for my lower arms. I want to use 2" on the lower and i want to use 1 3/4" on the upper arms with flex joints and poly bushing. would a y link set up be good for the road or should i go with full frame 4 link? offroad ltd here in denver said there bolt on kit for chevy straight axles is a y link with coil overs and they have them out on the road with no problems. just need a few more opinons! this set up is going in my 71 scout and im using 1 tons front and rear with full coils in front and 88 blazer srings in the rear. thanks for the help everyone.
