yeh gonna redo everyting measurement wise. One of the guys at work pointed out because there short skirt pistons you get a lot of rock, he asked when I measured the items did I measure them on edges or centres I said edges, so he reckons rock the piston full aft measure rock the psiton full forward and meausre, he believes I may have measured pistons at different rock angles. He can see differences of maybe 5 thou but not 21". Remeasure and go from there
