lug depth is .725. Yes, what little I drove the other one around, it"s like shut up and hang on. Maybe make Duluth ski hill ? Yes, mods on drives, I took a drive out of 340 Invader, drives fit perfect, located on shaft in right spot. 4.75 spread from center of drives. Two outside idler wheels, moved to outside of lugs, used 2 collar assy. to hold in place. Left pipe spacer between drives. Suspension will have to move idler wheels to run by lugs not on lugs.
