Engine swap

Does any one know if a 85 Honda 125 4 wheeler motor and tranny bolt up to a 84 Honda 125M 3 wheeler frame? After some research my tranny has grenaded. Looks like I can get a 85 4 wheeler motor and tranny for about $100-$150 from a guy. The only No HI/LO range and it has reverse. Frame mounts on the front seem to be the same. Any Ideas? I have researched alot of the part numbers on various parts and they also seem to be the same. What do you guys think? :?:

i'm not sure if it would fit but if it did that would be sweet then there would be no more pushing it backwards reverse is always something nice to have.good luck
