    I'm looking at putting a 6" lift under my '82 and need to be sure I order it right. I've got heavier duty differentials under it but it doesn't look like anything has been changed as far as the springs go. Do I order leaf springs as if I had factory differentials under it?

    Do your current springs fit ok? If so what would be the difference? If you used simmilar perches on you new axle, and they were the correct distance apart, I dont see why they would not fit properly

    Waht heavier duty differentials do you have? I'm pretty sure that all of them are the same height, except a Dana 60. I think a D60s perches ar ehight, so you may want a 5" in the front and a 6" in the back.

    I've got a 14 bolt ff in the back and believe a D44 in the front. Both have the eight lug wheels. I guess I'm wondering if there's a way to tell if there is anything different about the perches that I need to look for (locating pin size, etc). It would make sense to me that springs for a stock setup would work but I'd rather not pay the extra postage just because I didn't check.

    If you still have your old axle you could measure them up, and see if they are different.

    I wish I had the axles or even knew who went through all of the work to fix up the drive train in this thing. They did a lot of work but there is no history on where the parts came from. It really can make buying parts an experience. I've learned to ask "If this doesn't fit, can I bring it back?" whenever I buy something.

    Smitty, when I installed the 14-bolt and Dana 44 in my '75 K5 the only thing that was different was the size of the u-bolts, due to the larger diameter axle tubes. With the correct u-bolts both axles bolted right up to the factory springs.
