I spent some time looking through a bone-yard with a tape measure. It's been a while, but what I found was that most newer full size trucks (F-150, Silverado) were too wide and compact trucks were too narrow (Ranger, S-10). Some of the older full size trucks were pretty close, but I didn't find any with seats that weren't trashed.
I think Dodge Dakotas were pretty close too.
My advice is just to measure your truck and head out to the yard and start measuring.
