Mine came out of a 1985-1986 S-10 V-6 Blazer. It is, of course, Non World Class (NWC). First is: 3.76, second is: 2.18, third is: 1.42, fourth: 1.00 and fifth (overdrive): .72. The number on the transmission is: 1352-145 ML3.
I have it coupled to a 3.55.1 Chevrolet passenger car rear end. I'm running 15" wheels with tires that are 28.3" diameter. In fifth (overdrive), I'm turning about 1950 rpm at 65 mph.
I am very pleased with it.
