I have an 1986 JD 420 with a Cessna 9/16" smooth shaft pump. The coupler connects it to the Linamr 790 engine that has a 1" x 15 spline shaft. I am in need of a new coupler and have had no luck searching web sites. Any ideas out there?

Grainger has a 1 3/4" long 15 spline coupler hub. That could be welded to a similar 5/8" bore hub, but they are spendy.
