The rear springs are the same length, so the Should bolt right in. If I remember right, the mounting perches for the '73 and up rear ends are farther apart. So to use the newer rear end, you would need to put new repositioned perches on for the rear end to fit. Also, I think the newer rear ends are a little wider, but you might want to measure everything to confirm this.

He is talking about an '86. Any '73 - '87 half ton springs and axle will work. If you use a 12 bolt ('73 - '80) instead of a 10 bolt like the '86 came with, you will need a conversion u-joint for the rear axle.
