Update: I spent the better part of this afternoon looking up all the fasteners used in the grill area in the Chassis, Parts and Accessories catalog. Took a little learning to get used to the book's definition of some parts ex. top, left and right grill pieces are called frames. Also if there is "mirror image" parts, the hardware for both is listed under only one of the parts.
I've made a list and now that I've got the sizes, types, finishes and lengths I can compare them with what I disassembled and see if I have any that are right.
One question: Were there any details used on the hex headed bolts, ex. grade marks, manufacturers marks etc. or were the heads plain?
BTW 1937P-U, I have the Restoration Specialties Catalog. I checked there fasteners and they appear to be a good source for spring nuts and hex sheet metal screws.
Thanks to all, next time I'll start with the obvious, Happy Holidays,
Howard
