I used the long air valve on the F450 as intended. The holes in the rim prevented me from going straight to the outer tire. So I put two thumbs on it and bent it about 3/16" so it was sticking out of the hole in the other rim and breaking it. I solved the problem with another long air valve. I took out the core, wrapped two small ones Pieces of wet rag around each end to prevent it from screwing the o-rings, took my wrench, heated it up and flexed it, once cool put the rod back in making sure the small end is sticking out through the bottom any chance that you can replace the broken one for me after giving you all this useful information? :) Thanks Nancy.
