I have an early 70's MAX II I'm trying to rebuild. My plan is to put tracks on it with an 18hp or bigger engine. I have two complete lowers (with trans) that I plan on making one good lower. My other frame is an 80's max II with what looks like larger sprockets. The 80's frame is pretty much junk since the previous owner left it out side and let it fill up with water.

A few questions I have that I've tried researching...

Can I convert the frame to accept solid upgraded axles? Since I plan on running tracks, would it be a good idea to fab up my own axle extensions while I'm building it?

Can I use the sprockets from the hollow axles on the solid axles?

I'm sure I will have more questions as I get farther into the build.

Thanks
