EZ, I did in fact have the grease fitting in the van. I brought it home and now it sits on the computer desk, if you would like it, pm me with an address to send it to and I will mail it out next week.
(NOTE * I am NOT in the parts business!! - I offer this because I happen to have one and you can't find any other source - obviously I do not expect any money {not even postage}, I offer this to help you with your problem. As I said before, this is a used part that I salvaged when I replumbed a system, so it cost me nothing and I stole from no one (it would have ended up in the dumpster with the rest of the plumbing we removed if I hadn't taken it off). The assembly appears to be sound and in good working order and I offer it to you because I can't find the part listed elsewhere either and you shouldn't have to replace the valve when I have the peice you need to keep yours opperational)
