The big plus side of the alt 125 and 175 3 wheeler is that a lot of the parts from the LT 4 wheeler of around the same age will fit. That, and they had reverse. I think they would make a good hunting rig if it had at least a rear rack. I think parts are uncommon for them. I wouldn't call them a rare machine, but for some reason it seems like they are not the most desired. You never really hear a whole lot about them. I've got a 125 frame with rear end sitting under the barn, so they must not be that hard to find. LOL
