Just got a 1969 attex 297 machine has original motor but missing the tranny .There seams two be two types of transmisions on these buggys.I saw a picture of one that looked to me like somekind of direct drive no reverse the other is a big alumium housing with a lever coming out of it reverse?.I am trying to install a 16 hp vanguard motor and dont need reverse.So direct drive may be the way to get out cheaper.Not sure new to these machines and dont know much about them.hard to find parts
