Following this build. I really want to build a fully suspended 200e or es. They are my favorite machine in the mud and for doing yard work. The low range is really nice to have. Most importantly they seem to go many places that my 250es can't. I have ridden many hours on an 82 200e, but it has 2 bent rims and a bent axle..talk about a rough ride! I have a 200e roller that i have considered building up as a suspended machine, but that would not be right now, but maybe someday.
+1 on the trx swinger. i just replaced a 200s bearing carrier, and just buy eyeballing it, the carrier mounts look the same. Getting the pivot end to mach up to the frame might take some effort though.

This thread is a good read, and might be helpful for you. It details a 200es build with full suspension.
