How tall are you?

I'm 6'4" 245 lbs and changed the seating in my 64 Signet yet had a factory stock 65 Barracuda 4 speed without any change and was always comfortable.

I'm about 5'10" tall & wear a 34" inseam. I've got a '64 Barracuda & years ago my mother had a '65 Barracuda. I never understood why I had to have the seat all of the way back to be semi-comfortable in mine & in hers if I put the seat all of the way back I could barely push the clutch to the floor. Years later when I was taking my car apart I found that (at least on the driver's seat mounts) there are slots that allow you to adjust the angle of the seat up & back over an inch & also a 2nd set of slots that let you adjust the seat forwards & backwards on the brackets well over 2".
