Differential Torque Values
Good day all! Wondering if anyone has torque specs for the rear differential plate on a 1962 C1500 truck. Have a new gasket on its way, and want to do it right. Also curious to know if anyone has insight as to what rearend and gearing I might have. There is some info from NAPA as to what it may be. Any options for more efficient highway driving (I do very little - but want to drive her to car shows in nearby states)? This thing is geared for stump-pulling. Doing my best to keep the RPMs down on this big V6. Thanks in advance!

Re: Differential Torque Values
Differential Cover bolts should be 15-20 ft lbs

Re: Differential Torque Values
That NAPA gasket is for the Dana 44 and from your intro thread photos I saw you have a
Dana 60. Standard gearing per manual is 4:56 and Optional is 4:10's.

Re: Differential Torque Values
Once you remove the cover the ratio is stamped on the ring gear.
