When are you going to step up to Google Chrome as your default browser? All the cool kids are doing it.....
Johnny,Line 'em up over the bolt holes and you'll be fine. If you're over 6', try and position the riser as far rearward as possible while still allowing access for the bolts through the floor pan. That 1/2 inch of extra leg room will come in handy and it won't effect the carpet installation.
Holy crap, how tall are you?
LOL, 6'2"... least I used to be.... I moved my wifes Vert seat pan back as far as I could and still gain access to the seat bolts. Still a little short for me, so while I was replacing the pans/risers on my Coupe I decided to go further.... that's what happens when you have too much time on your hands....
