'65-'66 Proportioning Valve Piston

[OldGuy]

Does anyone know of a source for a "later" style proportioning valve piston (new)? A serviceable used piston would also work.

Let me know if you know of a source for a new piston or if you have a used one collecting dust that is excess.

Thanks in advance for your help.
