can't find 36 Buick radiator cap

My radiator cap is so corroded it has no identifying marks. I have called around and have heard it is not made in the aftermarket. any ideas where i can find a NOS or used one? thanks, Jim H

Just put in a new radiator, and a Nailhead. Problem solved.

 

Hey, how different is a 1937? Cuz Carquest Vintage Caps & Thermostats show 1937-1939 as a part# 33001. Zero pressure cap.
I dunno if that will help, but, it's cheaper than that nailhead swap.

But not near as cool.

 

There was a youtube documentary posted on here of a guy in Texas whom has SEVERAL warehouses on NOS-NORS vintage auto parts and more or less anything and everything obsolete for all makes of cars. failing that route pick up a hadr copy of Hemmings Motor News, they are still awesome and a great resource. Good Luck...
