Auto body repair & detailing: Part number question..., gm part number, wa number

Question
Ernie:
I've got a 1979 Chevrolet El Camino...decent shape, and I drive it a good bit.  Had a little fender bender recently, alas...and need to get a headlight bezel for the driver's side.  I thought about trying to bid for one on eBay, since they pop up there frequently.  But I want to make sure I get EXACTLY the right one, since they changed slightly every couple of years.
Is there a website or other resource where I can go to look up the EXACT part number for that year/model?
Also, I'd like to get some "touch up" paint (only got one little small scratch), and I wondered if there is a website or other resource where I can find out EXACTLY what color I need.  (Doesn't a car's VIN number have a code that identifies color?)
Any suggestions or advice greatly appreciated.
Warm regards,
David Gardner

Answer
David,The first thought that comes to mind for your headlight bezel is to try Year One.They carry new old stock parts as well as reproduction parts.Their catalog should give you the correct GM part number and also provide you with one stop shopping should you decide to buy the part from them.As for your paint code it is not found in the VIN.It is found on the sticker in the glove compartment.At the bottom of the list of codes you will find a number following the letters WA (ex.WA29)If this sticker is missing or if the car has been repainted ,your local automotive paint supplier or body shop may have what is known as a color chip book.They may have to dig to find one for 1979 but you should be able to find your color.(If your truck is two tone there will be two numbers after the WA number.)Good luck
