I have a 85'GMC Sierra 1/2 ton 4x4. I was wondering if you could swap in a 3/4 ton or 1 ton rears without any modifications. And if so, what modifications. Thanks

rear swapping

1/2 and 3/4 rear ends have the same width spring perches. A rear out of a 1 ton would work but it would need its spring perches cut off and rewelded. Check out http://www.coloradok5.com forums for awesome information regarding K5, K10, K20 and K30 parts swapping and technical information.
Good luck:)
