Buyer beware . The so called NOS 1967-1968 FORD MUSTANG SHELBY HEATER CONTROL VALVE in this auction is a used part that has had a half ass attempt to make it look new. It is also listed as a new part so there is no mistaking the meaning of NOS in the description . What with the appearance of the part ,the seller is ether clueless or trying to purposely perpetuating a fraud. It is one or the other. https://www.ebay.com/itm/334420000134 . The firewall side of bracket shows minor pitting corrosion of the metal which only shows up like that after bead blasting/surface stripping and with no zinc plating like original. There are also witness marks of the screw heads when the bracket was previously secured. The brass body has a odd tint to it which may be a coating sprayed on . The steel vacuum diaphragm was originally zinc dichromate gold. This one looks like it may be painted to mimic the zinc dichromate. A genuine NOS unit sells for 350-500.00 but this one if it holds vacuum , functions with the inside valve opening ,closing and is not corroded away would be far less not even close. I just didn't want someone here desperate for a NOS one to be fooled.
Maybe bot even half ass 8)
That might look nice for the east coasters, but us left coasters call that NOS ... Nasty Old SHI- . Used and abused, pimpley pok marks and all. Bummer/ :-[
