Atc200 rear end swap

[Fodge12]

So the splines on the end of the axle stripped out on my 1983 atc200, I have another 1985 200s and was wondering if the rear ends are interchangeable. Everything seems to be a bit smaller on the 85 so I'm not sure. Any input would be appreciated

well the bearings in the rear end are the same so technically the axle should slide in but as for the axle actually working because I think the 200s axle is shorter.

I'll have to measure them up. Thanks
