Thats a terrible pic but that's not a baby moon. Looks to be a 46-48 Ford cap. Baby moons are the plain,ugly caps that come on PepBoys chrome reverse wheels that retail for 38 bucks a piece....
Greg, I know you said steel artillery. The cast center and billet center Artillery wheels from WheelSmith have a much better look than the stamped ones. Just my unsolicited opinion.
With adapter to run small cap.
With large cap in 17/18.
