help ID 9" center

[boostinmalibu]

i picked up a 9" for my malibu, got it apart to see what exactly i have, upon searching the casting numbers on the inside of the center, i cant seem to find any info on it

just inside the flange area it has WAA 4025-B, pinion support has 4668-B on one side, and WAA on the other

any idea what it came out of? the housing wheel to wheel mount is right at 58", factory width, has not been narrowed, small housing ends, 28 spline axles, open carrier with a 3.10 gear

[boostinmalibu]

it may be a 3.00, i was told 3.10, ill go see what the bolt circle is and measure the axles

 

[boostinmalibu]
