i just recently purchased a 1980 atc 185 with a bent axle. i have been unable to locate a replacemet because it lists that axle as 1980 only. if i changed the whole rearend as an assembly does anyone know what other would bolt up if any ?

 

The issue seems to be how the sprocket mounts to axle
My bet in looking at different assemblies just change assemblies
The only thing to look for major different is sprocket size
It looks like 185,185s ATC200 and 200E look same
200m might fit but change whole thing as sprocket mounts change and possiblt same for 200s
200x totally different
Just look around
