wheeeeel screw up

I bought a pair of 15x8.5-5on4 centerline auto drag satin rims from SUMMIT back in 1991 and opened up one of them just to see how they looked closed it back up and never put them on the car till now due to finally getting done with the car.The problem is I went to put them on the car to find out SUMMIT sent me a 15x8.5-4 on 4 rim.Now I'M STUCK WITH THE RIM. Is there any companys that plug and redrill them.Thanks
