    So, I have a dana 44 and a 14 bolt under my blazer, I'm wondering what is necessary to run a 15 inch wheel.

    I know it's doable. I just don't need a 10 or 8 ply tire on my blazer. The most load it's gonna see is a couple dirtbikes or a couple snow mobiles. i'd like to be able to take advantage of the squishiness and cheaper/more availability of 15s.

    What about with a 3/4 ton 10B would you still need to grind?

    Minimal grinding only, mostly on the caliper bracket, not the caliper itself

    you can get 8lug 15" wheels from Summit for like $35ish each

    Sorry, I tried the search feature and really couldn't come up with anything, didn't see anything in the tech section so I figured I would ask.

    No, My next question is, if I swap to rear disk brakes, am I going to have fitting issues(the rear disk swap from the tech section using late '70s caddy calipers)

    The amount of grinding will depend on the backspacing of the wheel you are using.

    My rims are 4.25" BS so I had to grind a fair amount. I have disks on the rear and I had to lightly grind the casting flash off of one of my new calipers. I used regular 73-79 K20 calipers.:D

    Here is a pic of the finished grinding.:doah: :D

    There are at least 2 tech articles that address this.

    For a Dana 60 but same basic thing, and talks about 3/4 axles also.

    http://www.coloradok5.com/d60calipergrind.shtml

    Talks about switching to 8-lugs on a D44 or 10-bolt and discusses caliper grinding.

    http://www.coloradok5.com/8lugconversion.shtml


    About 5.4 seconds of searching found this 4 page thread discussing the exact same thing:
    http://coloradok5.com/forums/showthread.php?t=191768&highlight=caliper+grinding

    Or this 3 page post:
    http://coloradok5.com/forums/showthread.php?t=184406&highlight=caliper+grinding

    Or this post:
    http://coloradok5.com/forums/showthread.php?t=184836&highlight=caliper+grinding

    Sorry for the rant, but I'm going to puke if I see somebody ask this question again.

    Here is my 15" wheels on 1 tons:D.

    No pics of the grinding I did but it was a lot on the front. For the rear I just put them on no mods at all. I have the 13"X3.5" drums on the rear and 4.25" backspacing on 15X8 steel wheels from summit.
