65 dart GT seat position…

I had the same problem with my 66 Dart, only 6 foot but long legs. Had to drill new holes and move the seat back more than 2 inches. I then use 8-2 1/2" washers I found with 3/8" holes in them, one on top one on the bottom for each of the 4 studs to spread the load so the floor did not crack. Been that way for over 20 years now. Now my son who is 6' 7" looks like he is trying to eat his knee caps when driving the Dart, he can figure out where to put the seat when it's his car some day.
