The 79-83 i'm sure are the same but I think the 84/85 have a slightly different primary gear set up . its larger and shaped different .

I can see it has the larger groves in the primary gear shaft so I think thats a 84/85 tranny but it comes with the large primary drive gear so it should work in you trike .

so basically on the later atc 110 the shaft is larger

The splines are fatter/wider on the shaft .
