I have a 1972 Chevy K/5 Blazer Tub/Chassis out the 'Back Forty'. While it has no Engine, Transmission, or Transfer Case, and no Glove Box Door [ergo, no SPID], the Rear Differential was a 3.07 when I opened it up and counted teeth. This Blazer was originally an Auto Tranny truck.
Flint build.

Does your '71 Jimmy still have the SPID, and does it list 3.73?
