Steering coupler seal

Who makes that aftermarket spring-like retainer to hold ths steering coupler seal retainer in place? It loops around the bottom of the coupler and back over the retainer.

I know it doesn't look stock but I don't care, as long as it works. Crimping the tabs on the factory retainer in worse than roon canal. Anyone got any tips?

Steer & Gear makes a 1 piece boot cover for this application. It replaces the seal and the metal retainer. Price is $18.

Thanks, must have missed your reply. That boot looks like a winner. The factory type seal is a real POS when you try to crimp it yourself.
