does any one know of any places that make or sell on road wheel adaptors for a gbx sits would be good

Cobra is the only one to my knowledge. TRC used to make a plastic version but those are long since gone. Why would you want to run pancar tires on a GBX anyway? :confused:

RD Enterprises makes adapters for both front and rear. I have some and like them better than the Cobra ones (which are only available for the rear). Their web site is www.rdent.com
