Guys - I have a '57 Bel Air Hardtop....have for over 25 years! I never really had it on the road, although I drove it when I first bought it. I immediately started taking it apart and amassing the tons and tons of parts/sheet-metal to rebuild the entire car.
Fast forward to 'today' - the car has been through extensive rebuild and resto - including a custom chassis, etc., etc.
I remember 'how' it goes back together - and I have the help of the Assembly Manual - but the individual hardware??? The AM goes my the 5 or 6 digit numerical part number!!! No clue to what it is, other than the obvious bolt, nut, washer, etc. I'm not trying to return it to factory original - but I would like to use hardware as close as possible.
I have searched and searched - but somewhere there exists an index, or listing to convert form that GM Part Number to common hardware terminology.....right??
Please HELP - aim me in the right direction...
Thanks.

Been in the hobby for over 50 years, and I have never seen a cross reference from GM part number to standard hardware, except in some parts books where it says to source the item locally, and then they will give the measurement. GM was in the business of selling parts, not supporting the local hardware store. Many times, the bolts were odd ball lengths, and that makes it even more difficult to find an exact replacement.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

I'm going to go with 'probably' on that one. In addition to what junky said, the odd sized bolts were for a reason - the almighty dollar. They pay by the pound for hardware, why make it weigh more? If you save 2 cents a bolt by making it an eighth of an inch shorter, and you use 5 per vehicle, you save 10 cents per unit - times 1 million units - you save $100k just on that bolt.
