RE: would this fit in a rusty?
depends on what you meen by a little moding. a little moding to one can be changing a clutch. A little moding to me means that making a new chassis and acsesories isnt out of the question. Anything is possible it is just how much work it takes to do it. heck you could put a 10 hp briggs and stratton on there and it would be possible.
