I am looking to put 40's Chevy hub caps (baby moon type) on my 1942 1-1/2 ton big bolt truck. The wheels are 20" with 5 lugs in the front and 10 lugs in the rear. Would like ideas on how to mount them with out falling off. Does anyone know if hup caps came on the big bolts of that eara. Thanks!!!! for any help.
