being short (5' 6") i tried a couple of solutions to raise my eye level into the upper half of the windshield. the seatcover, cushion, pillow idea confirmed that i preferred to be a little higher in the car, but did not like being lifted out of the butt-pocket of the seat. my solution was to loosen the front bolts of the seat, then remove the rear bolts, insert about 1 1/4" stack of fender washers between the floor and the seat track (big washer, small hole, available in assorted sizes, most hardwares), adjust height to comfort by varying the number of washers, buy new bolts as much longer than the originals as the height of the stack. the angle of attack of the seat will be slightly changed, i personally found it more comfortable. if it bothers you, repeat for the front of the seat. before you tighten everything down check the door closure, gently, and the adjust of the seatback angle. my seat will not go all the way back any more, but as i said, i'm short, don't need the leg room, and it lets me put one of those neat little airport roll-alongs behind the seat. not the most elegant solution, but i wanted to get on with driving. painted black they would be invisible, mostly hidden by the seat anyway. if you wish to have some pretty aluminum machining done, this is an easily adjustable method to establish your comfort points and what will work for you, and give you the dimensions needed.
