I bought the front ones for my 56 f250 for $19.95 at Autozone, they wanted $29.95 at Napa

 

My 48F1 has a late 60's to early 70's rear end. Bought two wheel cylinders, brake shoes and both drums turned at local NAPA store for $48.00. Didn't think that was too bad of price for both rear wheels. Front is original, haven't priced front yet.
