    My friend picked up a dana 60 and dana 70 from a 81 chevy crew cab duelly. Is the dana 70 good for anything, what would we need to do to get it to work in a 78 Blazer.

    It is about the same strength as a 14bff but you have the option of going ALOT lower in gears /forums/images/graemlins/waytogo.gif

    What about width, won't the wheels not stick out far enough? Does anyone make a disk brake bracket for it?

    It depends, was it a pick up or a cab & chassis truck? If it was a pick up then the axle should be a D70HD which it a lot wider than a SRW 14 bolt.

    A combo that is becoming popular is running the dually D60 and the D70HD using unmodified Hummer wheels. I'll be running this set up on my K5. There have been a couple of threads on this, I'll see if I can find them. /forums/images/graemlins/thumb.gif

    As for the disc brackets, no one makes a kit for that axle but it can easily be done. You can use a weld on bracket or you can fab something on your own. I've converted mine to disc using front D60 parts but it required some fab work.

    Not GM dually pick up D70HD's. /forums/images/graemlins/wink.gif I believe the disc brake HD axles are 10 lug.

    weld on or bolt on?
    I took a drawing of a 14ff bracket and had it laser cut as a weld on for my D70
    there is nothing to brake brackets and they are cheap, those ones cost me $40cdn each

    I've often wondered if those brackets would work on the truck axle, it would make a nice clean disc conversion. Unfortunately, you'd probably have to pay someone too much for an axle they think is super valuable to get them. /forums/images/graemlins/doah.gif
