I'm 6' 3" tall. (Tall, tanned and handsome ;D) The head rests didn't seem to be a problem when I took the test drives. But after several drives of several hours or more I find that the back of my shoulders ache. I've raised the head rest as high as they go but think that I'll be more confortable with the head rest raised even higher. I want to remove then to weld an additional piece of piping that would raise the hieght of the head rest. Anyone know how to remove them from the seat back???? ???
