Valve stem caps

Is the Dill 627 the correct valve stem cap for the chrome Magnum 500 wheels?

+1 on Dill. I have different #'s also

According to information that I have been given the original cap manufacturer was  "Schrader". The Dill and Schrader caps are both yellow but are shaped differently from one another. I have examples of both and will try to post photos as soon as possible

Dill was the OEM mfg to Ford on the 66 as well as other years Shelby/Mustang stem and cap . The Dill valve stem has a Schrader type valve inside.
