    I am looking for some pictures of a ground Dana 60 caliper that was made to fit 15 inch rims.

    I know it can be done. A guy here at work "guarantees" me it cant be done.

    And I did search, you know what you get when you do a search that has anything to do with a Dana 60... thousdands.

    Thanks

    Excellent! Do you know what rim backspacing you have.
    Any more pictures anyone has, all the better to prove this fella wrong.

    Thanks a lot.

    Also, about how far down did you need to grind, 1/4 inch, 1/2 inch?

    Thanks again

    That's not mine. Someone here posted it but I don't remember who. IIRC this was for 4.25 backspace and I think it takes off about 1/8" or a little more. I saved it because this question is asked allot and if I go with 15" rims it gives me an idea what is required.

    Thing is... I hear there are two differant Daan 60 calipers. One that requires like 1/4 of the caliper to be removed and the other very minimal.

    Than there is the backing plate. Some people say no need, others say it requires a lot.

    Just wondering why there are so many differant opinions on this.

    As far as I know, D60 GM calipers are all the same, but, I could be wrong, I'm no authority. There is the Ford D60 caliper which is a lost cause for 15s, no way it will work. As far as I know, the amount of grinding, and whether the backing plate is a problem, are more a function of backspacing than anything. 3.5" backspace, very little grinding. 4-4.5 causes much more grinding and maybe a problem with the backing plate. That is my understanding.

    <font color=blue>I've got a picture of a D60 caliper ground for a 15x10 wheel with 4 1/8" backspace. Email me if you want it

    post it when you get it.
    I recommend starting your clearancing with new pads and rotors to avoid trouble in the future

    I don't have any pics to show but I have 15x10" with 4 1/8" backspacing on my D60. How much grinding depends on backspacing. If I had it to do over again I would have just used 3 1/2" backspacing wheels and saved a ton of grinding. with 4 1/8" I am not close to the backing plates and I think the backing plates would only be a problem on a 10 bolt or Dana 44 8 lug axle. When I step up to 38's I will get new wheels with 3 1/2" backspacing to get the tires out a little farther to help protect the body.

    The calipers are a fixed width... new pads and rotors will not change how wide they are.

    Yes, they are a fixed width, but they do "float" on the bracket. New pads will cause the caliper to "move" further into the wheel due to extra pad on the outside of the disk. If you have fairly worn pads and you grind the caliper to barely fit the wheel, then it will be roughly .200" further into the wheel when you put on new pads.

    True. But, I plan on grinding more than 'just enough to make them fit.'

    Dont want a rock or anything to get caugt in there and squeel and all. But, I will keep the brakes in mind. I think the Dana 60 that is going in has new rotors and pads. So, I should be good to go!!!
