I have a 1984 M1009. Runs great and I enjoy driving it except for one issue. I hardly have any room. I'm a bigger guy about 6'6 and 300+ lbs and when in the driver's seat I hardly have any room. I know the easy thing to say is well lose weight...working on it. However, I did not know if anyone has replaced their seats with aftermarket seats or seats from another truck. If so what years match up well and which years don't. There is a pretty decent junkyard nearby so I can most likely find a seat just wanted some ideas or opinions if anyone else has ran into this problem.
