I am not sure how tall you are but buckets can take out a bit of leg/head room compared to the bench seat. The tranny hump limits how far back and how low buckets can sit. I tried two different kinds (both Corbeaus) and they just took up too much legroom and had my head in the roof. I am just barely comfortable with the stock bench seat all the way back (89 reg cab). I am just going to hang on to it and get it reupholstered.

1989 reg cab pickup, 22re, 31s, 4.56s, rear ARB, rear OME springs, RS9000s, otherwise stock.
