    Default I have a rear end swap question

    I have a four wheel drive 1988 Suburban that needs a new rear end installed. I have found a rear end out of a 1994 Suburban with the same gear ratio and was wanting to know if anybody knows of any issues or problems I might run into. I already know the bolt pattern is different but am concerned about the width being different or if I will have to relocate the leaf spring perches.

    The bolt pattern is the same as long as they are 6 lug. and i would measure the width on the spring perches just ot be sure but i believe they should be close at least.

    I believe the spring purchase width is different between the two axles.
    This shouldnt be an insurmountable problem with a grinder, welder, tape measure, and an angle finder.

    I went and looked at one today that I ended up purchasing. The perches where in a different place but like tbplus10 said that can be fixed. The only real major issue was that it is a little narrower than mine but I decided that I can live with that issue. Thanks for all the help and input.
