73-87 seat in 60-66

[Evan's 1965]

Hey guys, I picked up a mint cond seat that came from a 73-87 truck. I was driving by & saw a garage full of stuff was being cleaned out & taken to the dump, so they let me have this seat. Not that I needed it, but didn't wanna see it get tossed. My '65 now has a really nice custom seat out of a 67-72 in it, which was a direct swap. My question is basically what all is involved to put a 73-87 seat in a 60-66? I've saw ppl say they've done it, but didn't really explain how. I'm mainly just wanting to know so I'll know whether to hang on to it or what.
