    Ok I used the search and I think I have my answer. I have found an awesome deal on a set of 3/4 ton axles for my 1500 Burb. Same year as mine, 1990. According to what I have read, these axles should bolt right in if I get the springs with the axles. Am I correct, or is this going to be a PITA swap? Both my driveshafts are variable length, but how much longer is the nose on a 14b vs. a 10b? I didnt have time to get measurements when I was out there.

    no need for the springs, Just make sure the 14 bolt is out of a 3/4 ton, and it will bolt in. and get the u bolt plates too.

    I've got a broken sping on mine right now, so will the 3/4T springs bolt in place of the 1/2T's?

    Yes they will and they might give you an inch lift since they are made or heavier trucks.:D

    Oh forgot, the newer 3/4 tons are 56" in the rear versus the 52 for the 1/2 tons.
    The front will bolt in, the rear maybe.
    :doah:

    1/2 and 3/4ton 52's were used up to the late 70's IIRC, then they went to 56's

    I know I have 56" springs on mine, but like I said, I didnt measure the donor's. From what I can tell the width of the spring is the same, so if they are 56" long I assume the same frame brackets can be used.
