Yeah, they do 3 seats with 3 belts the two end seats with the belt up by your shoulder- but only from 2000 on. I got mine out of a 1500 series but Suburbans, Tahoes, Denalis and the like all used similar seats. The front "bench" is really just a pair of shallow buckets with a jump seat in the middle-so it's three pieces. The buckets will certainly fit but I'm not sure if all three will - it could be a bit too wide, I'll find out later this summer.
Here's a set on ebay- though the broken sets are awfully expensive so this one seems high to me.
