I'm finishing up the dana and it's time to weld on the perches. My trans is 2 degrees down so I know where I'm at there. My driveshaft is 44" so I can get the driveshaft angle easy enough. I just want to try to work in some of the axle twist to set my perches right. Chris from New Jersey

I also need to add that the springs are moved in about 4 inches, and my front spring eye is about 1 inch lower than the factory mount, which makes the leaf spring angle more from the rear to the front than a factory mounted spring. This is one of the reasons I'm looking for about how many degrees of twist I should expect. Chris from New Jersey
