    I will be picking up my matched set of 1 ton axles next weekend. The d60 seems like it will pretty much bolt right up, but the 14 bolt seems like it may have some trouble. Will I need to replace and of the braking components for the swap. I see people swapping out the backing plates, is this necessary? I will be running 16 wheels on my truck too. So far I know that I have to get the funky 1310/1350 u-joint. Also I am in the process of doing a shackle flip, will I need to change the angle of the rear end or will the flip give the axle enough up turn so I will not have change the angle of the perch; I know I need to replace the perches on a 1 ton conversion too; just ordered perches too. Let me know fellas, winter is rolling up fast need to get the truck done for the snow. Later.

    Hmm, I thought some dorky dude wrote that cheesy artickle?? I must be missing something [​IMG]!! LOL.

    Anyhow, you need the 1330/1350 combo joint, not the 1310/1350. Since you'll be moving the perches anyway, measure the angles with an angle finder when you have it up under the truck and then weld it in place.

    I printed the article out, but why do I need to swap the backing plates? Also, isn't it a 1310/1350 u-joint, that what the aricle and everyone one else has said?

    You dont need to swap the backing plate on the 14 if thats what your asking. The E-brake issue is easy as hell to fix. All you need is a grinder to cut a slit in the backing plate mouinting hardware to get the old cables out and the truck E-brake cables in.

    1310 are for like 79' and older, maybe even 80'. But you have an 87' right? If so, 1330/1350 Napa part # 447. Trust me on this one. I tried the 1310/1350 first b/c everyone told me to, but nope, 1310 side was too small.

    I had to shim the pinion DOWN after my shackle flip, as did my brother.
