Default Re: GM rear gears
CBT is a 3.55 12-bolt posi rear from a 1970 Nova. The "E" stand for Eaton and means it is a factory posi. The "1" following the "G" stands for 1st shift. Some cars will have a "2" for 2nd shift. "1013" is the month and day of assembly of the rear. In this case 10 = October. 13 = 13th day.
