    just wondering how much work wouold be involved to mod a 99 with rear disc to fit an 89.
    Also i have heard you should look for a van axle cause it is wider
    my rear must have a bad bearing somewhere cause it is starting to groan when slowing into a curve, and every thing else back there has been replaced
    any ideas???
    thanks

    Not to sound like a smart-ass.. but anything can work if you have mean's.. ie: welder, cutting wheel etc to do some fabrications and modifications..
    I don't see why it wouldn't work though..


    I haven't failed, I've found 10,000 ways that don't work. www.rocko.rockcrawler.com

    I don't know of any reason of why it would be any more work than using an '88-98 truck rear end. either one needs the perches and mounts moved. The only exception is that you would have to change the brake proportioning, which might be as easy a getting the prop valve from the donor truck.

    Get out the measuring tape before you buy. Check the width of the axle, from flange to flange. The later trucks use wheels with a different offset, so the axles may be a tad wider to make everything fit properly.

    yeah, i knew i could MAKE it fit, i have a mig, torch, and assorted grinders, but was hoping to find someone that has done it, and could tell me some details.
    will my rims fit
    do i have to move the perches and shock mounts
    are they wide enough so dont have to have the wheel spacers etc

    thanks
