What was I thinking..........
OK I will go out on a limb here. First I am not ragging on large people and I see no problem in you moving the seat back so you will fit in what looks to be a cool Barracuda. My brother bought new in 1980 a Dodge Colt Sport. He weighs in at about 400 lbs. Over the years he has had the seat break many times. Bought a after market seat for it. Floor ripped out and had that re-welded back in (this is in Calif-no rust). Many many times I see people in a car that they do not fit-Why? Like the lady in her 60's VW bug. She is so over sized that she has to hold the steering wheel by wrapping her arms around it and holding it from behind. Why do large people buy small cars?
