    Are you talking about the rear or the front. Either one you need to drill a new hole in the top spring plate for the spring pin. Easy to do with a hand drill.

    I am talking about the front and will this change the angle of the drive shaft?? and would I just adjust the drag link to make it shorter .......( 1 inch) like the axle is moved 1 inch forward? thx

    I would say yes to both questions. I have never done it myself but I plan to do the rear of my truck and know what is involved with that but the front I would say the drag link will have to be shorter and I think moving the axle forward would help driveshaft angle more then hurting it. Hopefully somebody that has done this can give some real good info on this subject with the front axle. I am curious to find out if moving the front axle an inch or so is actually worth doing or not. Also if it is done that might be a good time to do crossover steering too.

    In order to move your axle 1" forward, you need to drill the mounting plate / casting 1" further back where the spring mounts to the axle. You will also need to make new retaining plates, (plates that go overtop of the springs) to account for the relocated spring pin. After you get this done, you will notice that, YES, that drag link is WAY too short. This is the time to go cross over steering. I am making mine right now for my Dana 60 an it appears to line up o.k. One last note: the pinion angle is going to go further down unless you put a shim in there or mill the flange. Roughly, 2 degrees from where you started. I went ahead and put a 1410 u-joint on my axle to allow for more angularity.

    E-mail mail me if you need any more info.
