I just purchased a set of original vintage keystone raiders wheels for my second gen. I was told to order a set of inserts to make them fit my application because the rims have oval holes in them. I took them to discount tire and they wouldnt even touch them and they said it would be a liability if they even put tires on them for me. is there something wrong with universal 5 lugs? and anyone know if it is still possible to get the little offset washers or inserts that make em work??
