There was a guy in the Chicago area that made some adapters out of a thick plastic material. I think they were done on a CNC machine , good bit of waste. They didn't work well on the 3 tab wheels , but did work on the 4 tab later wheels.
I didn't get much interest from the Mopar people in them and they were kinda costly. I think I may still have the guys number , PM me and I will check.
