This is some info the a fellow member sent me. I can sure use this type of info. Also this will help other going the cheaper route for this install like me.
Hi, one more thing i did to make sure I had everything right was to tack weld the cross member in place, install the control arms and spindle. At ride hide the lower control arm should be almost parallel to the ground. a 2x4 clamped under the cross member with C clamp will keep the lower control arm parallel. do a quick wheel aligment with a angle finder. the caster angle will move your wheel foward and back a little. set caster at 2-3 degree camber and toe in not very important at this point. put the fender on and wheel. if you got it right the wheel will be center in wheel well. good luck
