VCCA Home Forums Thread Like Summary - Could I get help I D-ing a rear end I just came across...

The guy I got it from specializes in 61 - 64 Impalas and he said it was 61-64. Casting #'s has the big GM with a T over a 7. To the left of that top # guessing date code I read it c or g 176 or 8 followed by 4 so my guess is C1764. Under that is 3725888. On the opposite side is a flat surface with stamped #'s BB0319. thanks in advance.

3725899 was used on all 1957-64 cars and became a parts replacement for 1955-56 cars,
