Thanks for the slag...and yes I do have a clue. I've had a few trucks in my day! You can swap a 60 into a 1 ton, if you want, but normally 60's were 3/4, and 70's were 1 ton. Ask any truck lover worth his salt.
...and it isnt the same as a "muscle car DANA" cause it doesnt have the pinion snubber provision. :butthead::crybaby:
If it came out of newer truck, then they're cheapin' out and installing 60's where 70's used to be.
