    Stephen, Could you tell me about the dana 70 front end. A bud of mine has a chance to buy one, should he? I have heard they are not as good as they sound but i am interested in your opinion.
    Thanks,
    Ryan

    Dana 70's have a closed knuckle. They are not terribly stronger than a Dana 44. The R&P should be plenty strong, but the weak knuckle ujoint is a MAJOR weak point.
    A Dana 60 would be a much better choice.

    The above is pretty much what I know about the Dana 70. I don't know what variations there are, but the ones I've heard of are closed knuckle and not worth swapping to. If it's going in a GM truck, it's hard to beat bolting in a standard GM D60. Check it out and compare the parts to a D60. That's about all I know.

    Most of them have drum brakes and most 70 frontends came out of Dodges, so there may be a problem bolting it up to a GM.

    H ow about cutting ends off of a D-60 and putting them on the D-70 with its 10 1/2" ring gear,35spline shafts and disc brakes? The Dodge and Chevy are close enough to make it work,if you think this idea is crazy, I know of someone who did that with a 14bolt FF, dont know the details I just shook my head as I torched the ends off the bare D-60 housing!!!

    the only thing you would gain by going to a d70 center is a bigger ring and pinion, and that's not a real problem with the standard D60 front. sounds like a lot of work for a really minor gain. It's hard to beat the standard recipe, bolt it a GM d60 and go flog it. The reason why people use the 14 bolt tubes on a 60 rear center is to be able to use 35 spl axles, but really, that's a lot of trouble when you could just keep the 14FF and clearance the bottom to be close (within 1/4") to a standard D60.
