What would be the correct colors painted on a 1970 489 case with a 3.23 gear? I believe the factory used to id the gear ratios by dabbing 3 paint marks on the bottom of the case?

Ask and ye shall recieve... ...Here's a list from an old mopar rag....

Thank you

Here's a Scheduled production date Jan 29th 1971.

That's a great example !!! Ratio color code and the orange daub for a sure-grip...Thanks for sharing... .......

Screamindriver, Do you have the same info for a Dana 60?

Thanks

Dana's had a 3.54 or a 4.10 ..Noted on the metal tag..They didn't have all the war paint an 8-3/4 has (unless Dream Car Garage did the resto). The date codes (and other info - see below) are hard stamped into the axle tube.
