52Carl, Since I'm using the old torque tub housing what would I need to do to keep the housing and make it like a later model housing under my truck. I've already changed the carrier to a 3:90:1 and have the 3:73:1 carrier on hand. I guess what I'm trying to do is to find the easiest and best way to do this. Jim Carter says" turn the springs around if I use the later housing. AT the present I have the original housing using the later model carrier (open drive) If just buying the new perches, with the off set hole and most likely new u-bolts is the way to go. Let me know what you think when you have the time. Steve H there are a number of ratios out there that work with the torque tube housing as long as you go to an open drive which is what I have. you have to find the right model and change the whole carrier. I did it and it works. Only trouble is what I'm having now. Broken weld, not too dependable. The spring perch that broke on mine was the one with the rubber in it. Hard to weld up good. I'm just trying to find the best way to do this and be reliable. Thanks to both of you. Steven
