Rear axle paint colors and dabs

I tried the search feature and struck out. Somewhere, I think on here but maybe not, I saw a chart showing a 8-3/4 rear axle identification paint marks. I’m going thru a 741 sg unit now for a new 8-3/4 I’m building and it has a large reddish orange dawb mark on one side of the bottom of the chuck and a bright yellow small spot on the other. Also written in red on the side reinforcement casting was a “99a”.

Does anyone know if what I remember exsist? And where I can find that out? I’d like to recreate all the marks but I know they varied day to day, line person to line person and car to car.
Thanks,
Joe
