how do i set the spring perches at the right angle??do i just have to sit the spring perch up on the axle and put one of those rulers with level o gauge thing on top and make it so the bubble is in the middle and then just weld it on(making sure the axle and the drive shaft are still in the stcok postion), becuase i dont want to f it up and have to grind them back off?? second question should i buy new spring pins and do the stock spring pins have enough room for a 4 deg caster shim in the front?
