Im about to buy a 93 fd but am not sure about head clearance. I guess I should have took my helmet with me for test fitting because when driving the car it seemed as if there was very little extra headroom. How much extra clearance can be gained from low seat rails and fixed bucket? Im around 6'2" and the car has a sunroof. Do people just remove the headliner usually? I know I should look for a car without a sunroof but this one is in great shape for a fair price.
