Does anybody on the forum offer rebuild services for 71-72 combination/proportioning valve or know of a service from a vendor? I would be more interested in an original 71-72 combination valve that has been rebuilt than a new square looking brass one that are offered nowadays. I am not opposed to the new brass ones, but I am a little concerned about it being correct for a long bed C-10 with disc in front and drum in back because they are usually listed as suitable for general purpose GM disc/drum setup. I posted a want ad for one here but thinking of sending it out for rebuild if I get somebody offering me one.
