CE 3 way rear drag shocks

It has the XHD leaf springs from Mancini in the back and pinion snubber. Last year we made a couple passes but had some engine issues. Back was up real high with the XHD springs and so we had the front up high too. We turned the spring hangers around and got the back down probably an inch and a half and the front down a couple inches. Hopefully having the front down lower and not so loaded will help weight transfer too. The torsion bars I cant remember right off hand. I think .92. It is a 72 Duster.
