3969277nf is the casting number of a 10 bolt.

CGA = 2.56 ratio non-posi

04 1 is an assembly date code, but should be 4 digits in 1970
04 = April
_1 = day of month

B = Buffalo assembly plant, 2 = shift?

This is a 1970 Chevelle 10 bolt with 2.56 gears. There should be a casting date on the rear of the center section on one of the axle tube webs.
