    I'm finally getting my hands on a 14FF. It is out of an 80 3/4 ton work truck. I know it has 3.73's but I don't know the condition. I am planning on putting 5.13's in it and running 39.5" TSL's. I was wondering what else I need to replace to get it in top condition. I was thinking new bearings and races but what else. Thanks in advance!

    That's about it. How about a set of disc brakes to loose some unsprung weight?

    I got my backing plates from misfit for $50 delivered. I think there are some others here that also sell them for a good deal. Do a search, some people here have done a pretty good job of documenting the job and it doesnt look to bad. Getting ready to do mine.

    Those are the main one's I know of. Beware of the last two as they are very expensive. /forums/images/icons/tongue.gif

    Yes, they do, but those calipers are very easily and readily available just about anywhere. It's the e-brake calipers that will be the most costly part in the kit.
    BTW, why pay for the calipers in the kit when they will mark up the price when you can get them at the parts store for around $20 apiece? /forums/images/icons/wink.gif

    Thanks for the replys guys. What exactly do you need to convert your 14FF to disc brakes. I know you need calipers and backing plates but what else? Thanks!

    1) Get the backing plates from any of the places mentioned above.

    2) Get 8-lug D44 (3/4 ton) rotors

    3) Get Cadillac Eldorado 1977 calipers if you want e-brake (expensive) or front D44 calipers if you don't want an e-brake (cheap)

    4) Get a pair of brake hoses and flare your alxe brake tubing. This is so you can remove the calipers and not pinch a line.

    5) Install, bleed and enjoy

    If I'm missing something, I'm sure someone will post.

    How hard hard is it to do a brake job on the 14 ff I have never done a drum brake job. Is there any info out there on this.

    It's just like doing a front axle disc rotor swap, only you need a different socket. You've got to take the bearing part apart to get the drums off.

    Thanks again for the help! So I won't have any machining to do? The D44 rotors will fit? This sounds very simple. This is my next project so I am getting ready. Thanks alot!!/forums/images/icons/smile.gif
