Kept my 221 alive. Shortened np205 coupler, modified (ground inside ends of splines to fit) and used national seal number 40071s to make up the shaft size difference. $54 for a new coupler and $17 for the seals. Much better then trying to find a good used T221 coupler. Hope this helps somebody else.

It's been 10 years since I did this, last week I pulled the case to do seals and the input bearings. Still dry as could be around the 205 coupler.
