I have a 2001 Buick LeSabre 40/60 bench armrest style with built in seat belts in my 51 shortbed and they are a nice fit. Because they are power seats, I had to trim the metal on the front of the original seat pan to allow the track to move front to back. There was a little bit of bracket fabrication work to make them bolt in and custom fit the original seat pan space. I like the bench seat armrest bucket look combination. Its especially nice to put the baby seat in the middle when I go cruising with my little 3 year old grandaughter.
