Valve Stems

For a 1965 Chrysler, what length valve stem should I install if I plan on running factory hub caps?

Factory shipped with standard length with about 1 inch extensions. Readily available at about anyplace including Wally world.

Just use the long valve stems unless you want concorse correct.Those extensions are a pain and Ive had them at the shop when they stick when you check pressure and deflate the tire.When I ran the 66 Imperial caps I had to run the real long ones.Rocky
