Toy Hauler locking gas cap

Don't remember where I asked about locking gas caps for the tank on the toy hauler, however, I was having zero results finding one. Walked into the NAPA in Forks WA as we were heading home, and showed the guy the cap. He said, looks sorta like a 73 Chev. Opens his book, walks back, and comes back with a cap that looks like it will fit, and it does. Pics will show the number. 2014 Stealth with a 40 gal tank. Hope this helps someone else.
