[COPO]

Dan,

The zone and dealer codes I posted for Baldwin Chevrolet are taken from an orignal window sticker of a '69 Z-28 there is no question about the correctness.

I have 100+ buildsheets and window stickers from various Chev. muscle cars. All zone codes are 2 digits and all dealer codes are 3 digits. The use of zero's as the first digit in the dealer number has nothing to do with the location of the dealership geographically.

Here are 2 eastern examples that don't fit your theory:

Benson Chevrolet
Roswell, Ga
Zone 08, Dealer 036
'70 LS-6 Chevelle Buildsheet

Joe Bokeman Chevrolet, Inc
Buffalo, NY
Zone 12, dealer 049
'70 LS-6 Chevelle buildsheet

Here's a western one that doesn't fit your theory.

Smoak Chevrolet
Farmington, NM
Zone 10, dealer 775
'70 LS-6 Chevelle buildsheet

I could go on, but it should be clear.

fyi, Reedman Chevrolet in Langhorne, PA is zone 15, dealer 546.
