    As some of you may know my truck went up in flames on my way to Arizona. I am down for now but, there is another K5 in my future hopefully soon.
    Here is my question. I may have the opportunity to pick up a 2 wheel drive 3/4 ton to get around in until I can afford the truck I want. I was wondering if the 14 bolt in the 2wd would work for a rearend swap? My old truck had 3/4 ton but all the stuff came out of a 4wd. I just needed to know if there was any differences. Any input would be appreciated. Thanks.

    As long as the rearend is from a 3/4 ton donor truck, it will work. If you had a one ton, the spring perches are closer together and the shock mounts are opposite sides of each other.
    There also is a difference in 2WD and 4WD rearends. The 2WD shock mounts hang down lower than the 4WD's. Just if you have a 2WD rear, make sure your shocks, if you get new ones, are longer than the specified 4WD length. Generally, add approx. 2 more inches to the shocks for the longer travel.

    Thanks for the info about the shock mounts. I had no idea about that but I figured somebody would.
