I hope I can find it too. You can tell where your car was built by the 7th digit of your VIN. 13637 breaks it down as a Chevrolet Chevelle coupe 2 door. The 6th digit is the year so if your car is a 70 you will simply have an 0, 71=1 72=2 etc.. then there is the plant code as follows:

R = Arlington, Texas
A = Atlanta, Georgia
B = Baltimore, Maryland
F = Flint, Michigan
K = Kansas City, Missouri
L = Van Nuys, California
1 = Oshawa, Ontario, Canada

Then the remaining 6 digits are your production line sequence number.
For example, the first part of my chevelle VINs for both my Malibu and SS read the same because they both came out of the flint plant in 1970.
My VIN reads: 136370F. I might be able to help you out if you wanted to decode your cowl data tag as well. It doesn't tell you a whole lot but it will give you interior and exterior colors which is cool if you can't figure out what the original color of your car was. The funny thing is that for 1970 and 1971 you could not tell if the car was a 6 cylinder Malibu or an LS6 454 powered beast by the VIN or cowl tag. in 72 they changed the VIN again and used the 5th digit as the engine designation which is as follows:

W - LS5 454 V8 4bbl
U - LS3 402 V8 4-bbl
J - 350 V8 4bbl
H - 350 V8 2bbl
F - 307 V8 2bbl
D - 250 Inline 6

Most of this is believed to be true although with GM there were always some exceptions for some reason but I guess out of a million cars produced 40 years ago with spotty documentation it is possible to have a few oddballs every now and then.
