Howard,
Not that it will be of any consequence but I had a '49 International KB-1 pickup that required the radiator support to be mounted very similar to your '47. IIRC, the support pad consisted of two 1-1/2" wide by 3" rectangular metal washers with two roughly 1/2" thicknesses of rubber "cushion" sandwiched in between the two washers. The washers and rubber pads all had a 1/2" hole thru the center for about a 1/2" X 2" carriage bolt to slip thru. This entire assembly rested on the front frame crossmember and of course the support rested on the pad. once the carriage bolt was installed thru the support, pad and frame, another round rubber "washer" similar to a thin shock absorber bushing was installed on the underside of the crossmember along with a flat washer. A lock washer was not used on top of the flat washer but instead, the carriage bolt was pre-drilled with a couple of staggered holes for a cotter pin/castle nut which finished the assembly. I assume the holes in the carriage bolt were staggered to allow for the amount of "crush" on the rubber pad. If this support is similar to yours, the carriage bolt shown with it also includes holes for the cotter pin/castle nut assembly.http://www.ebay.com/itm/47-PACKARD-RADIATOR-CORE-SUPPORT-BRACKET-BRACE-/140493600538
