    Found this on Pirate. My buddy is looking for a C&C 14BFF is this what one looks like with the backplate flanges way in there? He is going to run C&C hubs as well with discs. Will the flanges need to be moved or are they ok right there?.....if not does anyone know how you move them?

    That looks like a dually two wheel drive unit to me. The flanges are way in to make room for the dually set up and I say two wheel drive because of the way the shock mounts are rotated downward as they are.

    My 14BFF looks just like that with the hubs off. The shock mounts are EXACTLY the same. Oh yeah, its the factory 14BFF in my 86 GMC K3500.

    i've got one in the garage right now that has shock mounts exactly like that. It was from a 2 wheel drive truck. It wouldn't go in mine without moving the shock mounts upward. The shock body hit the mount/axle tube and wasn't even close.

    I've only ever seen shock mounts like that on 2wd 14 bolts.

    I got my 14bff from a '76 2wd and it bolted right into my '89 Suburban with no problems. hmm, that looks like it either goes to a newer style truck or a different one all together?????

    Yeah I know it's from a 2wd, but is it a C&C and do you have to move those backing plate flanges with C&C hubs to run discs?

    you should be able to dry fit/mock test fit everything in order to get measurements to see where the backing paltes need to be attached at on the axle tubes

    someone who has doen all this needs to eleborate on how exactly /forums/images/graemlins/laugh.gif

    good luck

    oh and those shock mounts look normal to me too, 73-up staggered style, common normal

    Guys, the shock mounts on ALL 1 ton 14FF axles are lower hanging like the 2wd's. Its the 3/4 ton 14FF's that have a higher and lower hanging shock mount. Thats it. All 1 ton rears have the same length shock mount. /forums/images/graemlins/waytogo.gif

    If they were not in the way, I would just put 2 new flanges on there and leave the old ones.

    Yes they will need to be moved/replaced for the disc swap.

    I agree. The flanges in the top pic are obviously not in the same location as the ones on my 3/4 ton axle.

    Well the hubs are 2" narrower than a SRW hub so that looks like the flanges are about 2" farther in too. So with C&C hubs will disc brackets work?

    To move those flanges just grind the welds??

    Or have a spacer made. I believe around 2 3/4" spacer would be the right width to fit to the SRW bearing hubs. /forums/images/graemlins/thinking.gif

    Yes, then use a BFH.... IF there is the slightest chance you may want to run a dually set up, leave them on there. /forums/images/graemlins/whistling.gif
