I swaped my 53 16in. wheels for some 15in. wheels that have 3 bumps where the hub caps pop on.I ordered a set of baby moons for 15 in wheels ,10 1/8 in. inside, that was supposed to fit but were to small. Can someone tell me the yrs. of trucks these came out on,or even better where to get some babymoons to fit the truck. THANKS
