For the windshield I bought one from CountryATV a few years ago that was made of Lexan and it has heldup very well. Unfortunately they stopped making them last year. I don't know if anyone has put a predator engine in a Max, but they seem to be darn good for a Chonda motor. Maybe a route for you to look at. I bought a trencher with one on it 2 years ago and not a moments problem.
