Been up and down with the rear end 100 times since sunday and there is no binding anywhere even if I raise one side and not the other. The reason I went back with the forward mounts is to get the rear end up in the chassis as high as possible without having my upper arms pulling forward at all. I angled the uppers at about 30* to the center to give as much lateral support as possible on cornering. I had an engineer working with me the whole time and he was the one to suggest the angle on the uppers(he wantd 45* but I swayed him from that).
If you look at my tubs there was a differance in those as well I had to take 1.5 inches out of one side and 2 out of the other to get the tubs to be the same size(damn 70's quality control) My rails line up until they start to turn up in the chassis thats when the offset starts. But I muasured the leaf spring mounts to the rocker and they were even but the frame rail to rocker is offset. So they had the leaf spring mounts in the car centered properly But not the frame rails.
No it's not tube length that was my issue it was my lower mounts from one side to the other. say for the sake of arguement I had my housing finished today (I don't but lets say I do) My lower mount on the drivers side is fictionally speaking 2.5 inches from the housing end and my passenger side is 1 inch from the housing end.(exactly no but about 1 to 1.5 inches Don't have the housing in front of me right now to say exactly)But everything else in the car lines up perfectly the arms are parallel to each other and to the frame rails and the rear end is perfectly centered throughout the travel.
Andrew I am building up the floor pan in this area with some 3/16th plate and tieing the cross bar to the floor and to the old pinion snubber support I will post those pictures when I pull the axle back out.Also having the bars go out would give you an even shorter bar to work with Plus unless the center section is made for it moutin gthe upper arms on the housing on a Dana rear end is a pita
