decoding vin numbers

i have a 65 impala ss with a vin number of 166375d120727. i know what the numbers stand for but as far as the d it does not tell me what assembly plant it came from. help me find out.

thanks,

Something wrong with the d on a 65 Impala. Here's what I got:

166375d120727

1= Chevrolet

66= Impala SS

37= 65-66 sport coupe

5= 1965

d= the building plant- there is no D letter code

120727= production sequence beginning at 10001

PLANT LETTER CODES

A = Atlanta, GA

B = Baltimore, MD

C = Southgate, CA

F = Flint, MI

G = Framingham, MA

J = Janesville, WI

K = Kansas City, MO

L = Los Angeles, CA

N = Norwood, OH

P = Pontiac, MI

R = Arlington, TX

S = St. Louis, MO

T = Tarrytown, NY

U = Lordstown, OH

W = Willow Run, MI

Y = Wilmington, DE

Z = Fremont, CA

There is a Doraville plant but they didn't make Imaplas

I don't know why you say Doraville didn't make Impalas. They did in 1966 and continued until 1969. D is for Doraville. Perhaps its a '66? Pat

I know. That's the weird thing, it shows Impalas in 66 but not 65 as I said. But his VIN showing 37 could be reflecting that the 65 was a late 65 and one of the 1st cars built at Doraville even though they officially started with 66 models.
