1938 Radiator cap

[cadillac60]

My 38 Cadillac V-8 calls for a 4lb  bayonet type rad cap.  I have done a search & so far can't seem to Zero in on one. If someone out there can direct me to the right place I would appreciate it.

Bruce,

Take a look on e-bay, search for radiator cap rc4.

One that looks good is item #:221138237514

The 37 and 38 had the one inch long neck.
