Aftermarket seats..what type do U have?
Right now, getting the seat LOW enough is the issue. I have a 1 3/4 rise in the drivers side floorpan. As a result, I need to get seats with REALLY low profile brackets to keep the height down, and build a spacer for the outside holes to match. Below is his driver side (red) and my driver side (brown and dirt). Notice the LARGE rise to the toward the trans tunnel on my car.
