Found Early/mid 70s Proportioning Valve U-Cup Seal

[texarback]

All, I'm looking for the U-Cup seal for this proportioning valve. If anyone has this style and can open it up to get to the seal that would be awesome. Or, if anyone has an old valve laying around and wants to send it my way just let me know what I owe. My valve works but I need this seal and am having a hard time finding one.

I started a thread back in November.

Proportioning Valve Rebuild

I have this AC Delco Proportioning Valve (Part # 172-577) that works fine except the "O-Ring", if you call it that, is split. Does anyone know where to source parts for these things? I assume they were meant as a consumable that should be replaced if a failure occurs as I can't find anything...

I have a couple frames with prop valves I can pluck easily (76 C10, 77 K10). I may also have a random one on the shelf. $15 shipped.
