What rears in a 3/4 ton 4x4. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

what diffs would a factory 1964 , 3/4 ton , 4WD, 8 lug truck have in it ? also which transfer case? >>>>>>>>>> I gotta think any 3/4 ton truck from that era would be built pretty hefty. And pretty rare to even find one. thanx , crossy

The rear end could be either an Eaton HO52 or a Dana 60. Does it have a drop out 3rd member and a round cover on the back? If so it is an Eaton HO52. The Dana 60 cover will look just like the cover on the front differential, just slightly bigger. I believe the transfer case should be the NP221.

Should be an HO52/Dana44 Rr/Fr combo. The transfer case/transmission combo will be Rockwell T221/SM420,unless it has the standard 3spd on the column. They are very stout and not so common to find. Where is it so I can buy it?

tim, the truck was flipped and 75% of it is damaged including the cab. he wants too much for it i guess because he bought a crate engine 10K miles ago. I wanted it to put one of my spare cummins into, but the body is toast. i know i can sell off the engine for DECENT money, but once i found that the cab itself was damaged , i kinda wrote it off.
he wants $2500 and it's less than 60 miles from you so if you want the link let me know, thanx, crossy

Hmmm...I'm getting the hots for one,but good body parts are my main concern. I'd like an original,but I do have a newer 4wd frame/axles/drivetrain already. I'd consider it either way in better economic times,just to have the potential of building an original-ish truck.
