I read in an old classic trucks magazine the other night that, "Without a doubt, seats from 88-94 Sierra/Silverado are one of the easiest and best ways to upgrade any 60-72 Gm truck seat."
I agree! These are the only seats that look right in my opinion of course other than stock. Matter of fact most cars and trucks older than like 1970 look rather off with high back seats. Those era of Chevy seats actually have somewhat of a low back and look proper. I had gotten a set of seats off a 98 Tahoe Split Bench but ended up selling them. I just couldn't see me with those high backs and drilling all kinds of holes in my stock C10!
