Hey Matty, The bullet on the centre cap is a MOONS 2 3/4"x3" Bullet. You can pick them up from Johns rod & custom or Kustom City. Cost can be anywhere from $35 to $58 depending on who you know. The last lot I bought apparently were the last they were making, But I doubt that no one is making them. There is another brand, I think called Kalifornia Kustom that make Caddillac bullets. Check with the online sellers of kustom bits.
