It wasn't till '68 till the 3.54 ratio became available in 3/4 tons, but too late to save the reputation. A 3.73 for 3/4 tons would helped also improve gas milage for these high torque at lower rpm engines.

Very true, I can say my truck is geared too short with 4.10's. A possible project this summer will be to replace with 3.54's. Interesting the 3.54:1 Dana 60 was finally made an option in '68, but only for 2500's with the 351E V-6.
