I was able to find some similar info from 1970 cars showing:

New Union Chevrolet
1615 Independence
Kansas City Mo.
Dealer 570
Zone 05

Niesbeth/Siedel Chevrolet-Pontiac-Buick
610 South Main St.
Trenton Mo.
Dealer 596
Zone 05...I think they had a satelite store very near by as well that carried another Dealer & Zone code too,which may be your initial Dealer request.


Hope this helps you out some.
