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.
