What's the lowest profile bucket seat?

my buddy made brackets to bolt 98 civic seats in his stock floor s10 right to the floor. It looks pretty funny b/c I am 6'2 and he is 5'11 but both of our shoulders are just a little higher than the windows in the truck. So it looks like we are both about 5'5 while sitting in it, but once we get out it is a completely different story

In my old 88 yota I had a 5 1/2 in body drop to the doors and I ran miata seats. I'm 6'2 and still had head room.
