Fellers, newly acquired 69 bird. Manually determined that my gear ratio is 2.78:1, but I was really hoping to find the code to confirm. 54 years of grime was scraped away and degreased, but I couldn't find any 2-character code anywhere. Not on the axle (front or back, passenger or driver), not on the rear wheel hubs (not that i could see anyway).

Am I smoking crack? Should the code be pretty obvious? Can somebody help pinpoint where it ought to be?

The Pontiac manual indicates driver's side, rear, 3" from the pumpkin, but nothing there. It just happens to also be where they welded on the mounting clip for the brake lines, so I wonder if the code is tiny that some surly line worker in 69 welded right over the top of it.

It's becoming personal now, but I should just let it go...but I can't. Appreciate the help.
