I've got an old chevy throttle pedal (floor pivot type) which i was going to try to use , along with some form of swivel/pivot/whatever to get the right "direction of movement" if that makes sense?
I didn't really want a hand lever, the steering is pretty sharp and i didn't want him taking his hand off the wheel to go looking for a lever.
Mind you, I do have a couple of spare Ak magazines in the shed......
A bullet might have your name on it, hand grenades are addressed "to whom it may concern......."
You can never have too much red wine, too many books or too much ammunition.
