(ps the bottom bars go forward and the top bars go backwards)
this is how the bottom is bolted up
this is where the front of the leaf spring was bolted to the frame.there was a bracket welded there to bolt the bottom bar.
this is the center axle. there is a bar welded over the axle to each side to bolt the top bars.(this bars run to the back of the van)
this is the left side from the axle to the back of the van
this is the right side notice on this picture there is a frame support right behind the compressor. this run between the the stock frame to reinforce.this where the rear bracket is welded next picture might help more
