SBP Slotted Wheels 14X6 or 14X7

Looking for two SBP slotted mag/aluminum wheels that are or are similar to the old Shelby 'Cal 500' slotted mags. I got a set of 4 Shelby 'Cal 500' mags from swamp meet, but two had the center hole machined out too close to lug holes to be safe long term. But what do you want for $60 for all four?

Looking to replace these two when I find a suitable pair. Would need 14X6 (the size I have) or 14X7 or 14X8 would work since they will be for back. In CA & need to ship. Thanks.
