I have some rear wheels that need to come off of a 42 COE and I can't see any lugs. A friend of mine referred to them as East Coast Wheel type that were snow friendly. I will post some pictures if necessary, but does anybody know which type wheel I'm referring to, and how to go about getting them off? All I cee are the 8 lugs on the rear center "hub". All 6 on the truck are the 3 piece locking ring type it appears and they seem to be cast iron wheels. Thanks
