4 spd ID help

[66 Charger]

The housing has stamped on it 2468372. How would I go about trying to ID the housing? Or do you know what it's to?

Thanks,

I googled the number for you. What I found shows that number (2468372) for a big block bellhousing for an A833 4 speed in 65 and 66.
Can't verify the accuracy, but it came from a Mopar-related web site
