my buddy just picked up what he was told was a '69 half ton rear end for his truck. (his truck is a '53 1/2 ton with 350 and 4 speed manual tranny from a '74 1/2ton)

apparently it was basically given to him for free. but we cant seem to nail down what the gear ratio is, the net has conflicting/confusing info. didnt find any sort of part number either. and dont have the truck it came off of for reference.

he's worried about the 3.7 being too low for highway driving and is hesitant to install. anybody know what that ratio was if it is from a '69 half ton?

if it is a 3.7, is that too low? i remember doing freeway 70mph or so in a '68 half ton with my uncle when i was a kid so it cant be that bad right?


'53 3100 on '93 S10 chassis- 4.3V6 +4L60e
