I am getting ready to put new seats in my K5. The PO had welded in some from a van and they are too high. Can someone measure their stock seats from the floor to their ass when seated? Or, if your aftermarket seats fel good to you, how high are they ffrom the floor. I'm 6' 4" so I'll need to adjust, but I m looking for a good starting point, and then I'll go from there.
