I bought the 4 - 7in. wide Aluminum Slotted Wheels last week for my 1953 Chevy 1/2 ton (3100 series) Panel Truck. On the inside of the wheels they say 15in. Made in U.S.A. , RWI. Is this a brand of wheel ?? Also the wheel studs are about a 1/4 of and inch from just being flush with the outside of the wheel, so that means from what I measure and can see I will need a chrome lug to be a 1 1/4 long plus the thickness of a chrome round type washer. Does anyone know off hand what size the wheel studs are ? meaning nut size. Thanks for any help with this. once I have the nut size and right chrome lugs and washers then I can order them in a kit from Summit Racing.
