Front Seat Issues

You have this problem and you are only 5'11"???

Two suggestions.
1. Put a small spacer (1/4" - 2 or 3 flat washers) under the front seat mounts. This will tilt the back quite a bit and might help.
2. Maybe redrill some holes in the floor and move the whole seat back a couple inches. I will take a pic this PM of what your seat holes might look like (from my '72 Duster). I am thinking the seats bolt on top of a high spot, moving them back might also drop them a 1/2" or so.
