atc90 cross compatibility

[n10sivern]

i have a 1971 atc90 which my parents bought brand new that i plan to restore after my dad gave it to somebody to work on and they essentialy junked the bike. mechanically, are all the major parts for the atc90 the same throughout the years? what parts from a 70 or 110 are the same? by major parts i mean the carb, airbox, recoil starter, etc. also, are the connection points for the fender the same throughout the years or the same as any other trikes as i need a green fender. any and all help greatly appreciated.

basically all the 110 stuff will swap to the 90, except the newer 110s like the 84 and 85s. But I know the 79' 110 shares many parts with the 90, like frame, carb, axle, carrier,forks etc.
