Not trying to be nitpicky but 15 inch Corvette rims were 8 in - inside to inside of bead. Am thinking of the common '68 - '77 Corvette slots. 7 in were used mostly on '70 - '77 Monte Carlo. If you were closer - and that Chev slotted was a 7 in, I'd buy it, I have a set of three.
They likely did have a variety of sizes. Pre '68/'69 Corvette. Was mentioning the "common" seventies slotted rallies.
