So the steering wheel on my '65 is right up on me. It actually hits my belly. I am told there are seat extenders available that will back the seat up a few inches. Anyone done this? What seat extenders did you buy and did they work? How much room did it buy you? I'm not very mechanical - how hard was it. I'm in Maryland - if I pay a mechanic to do it, how much can I expect them to charge me?
