    I read an article on here once about swapping a Dana 44 and FF14 bolt into a 1/2 ton (with 10 bolts) and it mentioned having to replace the backing plates (with press in style from a SF) on the rear axle when installing it on newer Chevys. First, what is considered a newer Chevy? Would I have to do this on my 82? And what is the reason?
    Are there any other complications I should know about before doing this swap?
    Thanks

    I believe (correct me if I'm wrong people) that the press in backing plates are referring to the e-brake cable. Most FF 14 bolts had bolt in style e-brake cables and I think (don't know for sure) the 10 bolts had press in ones. In order to use the press in style you need to get different backing plates or adapt the FF to work with your existing setup on new Chevy's. I don't know because I have never had a 10 bolt rear (lucky me) so I don't know for sure how the e-brake cable attaches. I would assume though that on your 82 you SHOULD have no problems adapting the 14FF to your existing e-brake cables (again please correct me if I'm wrong people). If you do, a machine shop should be able to make adapter to mate the two ends for cheap $$$. Let me know how you make out.

    If you didn't build it yourself, how can you call it yours.......?

    Well I installed a 1980 14FF into my 75 K5 and the e-brake cables hooked right up.

    Just covered this ground with my 91 suburban (push in style).
    Found an 80 14bolt FF.
    The 80 has the bolt in style, equal length e-brake cables. the Suburban has push in (for the 10 bolt).
    I consider E-Brake optional equipment (automatic).... so until i get a bit more time, it's on the back burner.
    Think i'd have a hard time finding the special backing plate to take my 91 push in.
    here's a link to some folks who make 'custom' cables. I plan on getting with them soon to see if they can just fab some up. Understood someone posted it to be about $40.

    E brake? What's an E brake? I cut that POS off a long time ago.
