i havent mounted it yet, but i have one of those seats ( i think we are talking about the same one) it fits nicely. i am a big guy and it does get me pretty close to the roof, possibly even a little higher than stock, but i know i will jsut recline it a little bit. it is pretty close to just bolting in. the seat crossmember has holes in it already, so i jsut need to toss some bolts in
i do have an extra cab though
it does recline, they also slide forward and backward
i am 6'3" tall and my legs are way long. the inseam on my pants are 36"
