I have a rear differential from a 65 corvette and am trying to see if it is original to the car. Cast marking on the input side seems to be ‘389914’. Near the driver’s side output shaft shows ‘B65’. The vin says this car was built in November of 64 (102243). Can I get some help here from the guru’s?
It could also be 1975, IIRC that reinforced bracket didn't come out until 1968.Turn it over and get the stamped information near the parting line.
I turned it over and had to clean off some grime with some gunk remover and a wire brush, but I couldn't see any stamping on the differential body-side of the flange. Looking at your picture, I'm not sure if I should have been cleaning up and looking at the cover flange. I'll take another run at it in a bit, but if there is no stamping, does that tell any story? Perhaps a GM replacement part?
