I have always thought that my 69 Z came from Scott Chevrolet in Downtown OKC.
My dealer code is 833. NCRS does not have any info for which dealer is 833. At one time, I thought it MIGHT be Seltzer (where fathom green ZL1 was sold) but that is dealer 835.
The dealer emblem was already removed when I got it. I welded the holes shut before painting. But, I did record the dimensions. Don't have them handy, but can find them (maybe).
Check out this page from NCRS.

Dealer 832 is Scott's Chevrolet that was in Prague, OK, about 40 miles NE of OKC.
Makes sense to me that Scott would be 833.
Hoping Paul will chime in here.
The Scott family is STILL in business in OK. They have Frontier Chevrolet in El Reno, which is about 40 miles west of OKC. One of my best friends has the Buick GMC dealership in the same town.
If anyone has an old Scott Chevrolet dealer emblem from the late 60's, then the measurements could solve the mystery.
