I originally meant to replace one single valve stem cap on my truck. I had finally noticed after a couple years that one of my caps was completely different than the other 3. I set forth to make a replacement... I just happened to set one of the caps I was going to make a copy of on my bench next to a 45 round. After I got done setting up the lathe, I looked over and saw the two next to each other, and decided what I had to do! The first set for my own truck was really easy to make. They are to SAAMI specs, exactly like a 45 cartridge. This is what they look like on my stuff.
