I’m making another few cam lamps and want to use a cam gear/some sort of engine gear as a base. Must be steel so I can tack the cam to it. Preferably 4-6 inches in diameter. If you have a GM LS cam gear (any 1997-current LS, LQ, LM, f-body/truck/van motor) that’s awesome as it looks that much cleaner, otherwise I’ll take what you got.
