    Anyone one done a good write up on this also how do I tell the differance between a sf and a ff 14 bolt will that make a differance in adding discs?. I'm picking up a set of 3/4 axles out of a 79 alonf with an old 8 lug ext. hub d44 for $150 this weekend:D and I'm thinking of doing a disc conversion on the 14 bolt

    Very easy to tell the difference.

    First off, the 14SF didn't come into being until 1982. (believe that is the right year)

    All 14FF I am aware of have two bolt patterns...one is the typical wheel pattern, the other is the hub bolts. So you have the lug nuts, plus bolts visible from the wheel.

    The 14SF uses a 6 or 8 lug pattern, with no "extra" bolts, so you will only see lug nuts/studs.

    write on a 10 bolt but its all b asically the same. THe only difference is the parts needed and how they go on... I guess thats a big difference but yeah. 14 bolt FF is more difficult to do the swap on but its still easy. Its difficult cause you have the hub and have to press or pound the lugs out to seperate the drum and hub.

    sounds like I will be getting a 14 bolt ff than. Does the differance in 14 bolts change the parts needed for the disc swap?

    Required, not exactly...advised..it'd be a good idea. You should put in a prop valve to regulate how the rear "brakes" because you dont want them to lock up. Usually people flare it into the lines right under the master cylinder and adjust it there.
