Craig -

What is it? Midyear diff or cover? Sure it isn't 3830303?

John,

My car is a 64. The numbers came from the back cover near the top. I am not sure if it's my original differential or not.

Thanks,

Craig

Craig -

3830303 is the casting number for the '63- early '65 diff rear cover. The differential housing casting number (3818753-N) and its casting date are located on the driver's side of the housing, buried behind the camber strut bracket. Additionally, the ratio code and assembly date for the diff is stamped in the bottom flange of the diff, between the spring retainer plate and the strut rod bracket - will take some deep cleaning to see the stamping.

Thanks a bunch. That helps. *NM*
