Plymouthy Adams Posted August 31, 2017 Report Posted August 31, 2017 usually on the very top of the carrier on the flat of the boss is the ratio stamped...often in two numbers like 10/41 where the division would work out to be 4.1 and often it can be on the passenger side of the hoghead near the oil fill expressed in the actual ratio....

59bisquik Posted August 31, 2017 Report Posted August 31, 2017 Never looked at casting numbers, but both my 3.73 and 4.11 differentials were stamped on top of the housing. Quote
