control arms 64 c-10 help

[dlandez]

i brought some new control arms and i am installing them and i was told to align the hole on the shaft with the bolt head on the cross member clamp well my old control arms had only one hole on the shaft and new ones have 2 and the ones on the new shaft are farther apart than the two clamps on the cross member so do i align the front hole on the shaft with the front on the clamp or the rear one
