When you get mobile again, I can help you replace that last little oring. I've done it to two shut-off valves on my 95 606. A very small gunsmithing roll pin punch drives out that little pin allowing you to remove the stem and replace the oring. Do not try to drill it out. Simple fix now. The first time it wasn't so simple. Or, if you want to send me your old one, I'll send you one already to go.
