Post a WTB on RGP. I picked up a really rough Shadow about 6 months ago that was missing the rings and mongols. I found the rings on RGP but it took almost 6 months of checking everyday.
I'm still looking for the mongols is anyone has an extra set laying around. I know pinballdecals has a set but I think $75.00 is just a little steep for 3 plastic toys.
Good luck
