I have reviewed several years of previous posts concerning this subject. I am looking for the specs for the upper bracket washer and bolt. THANKS

Re: 1957 generator fastners

Jerry, The 1929-1958 Chevrolet Parts and Accessories Catalog, Section 2.277, says: "37-58 ALL, CORV.....WASHER (5/16) use w/3718205 Bolt)...3682643 2 .02," which means it applies to the '57 Corvette (and pretty much every other '37-58 Chevy), it's a 5/16" washer, with part number 3682643, the car uses two of them, and they cost $.02 ea.. The entry for bolt 3718205 says: "BOLT, brkt. to generator (hex hd. 5/16-24 x 1-1/4)....3718205 2 .07" Not sure why it says 2 of these are used. This same bolt is used on '53-55 Corvette for the same purpose.
