Any suggestions on which differential I should/could use for an open
drive line?
My truck is a '51 1/2 ton Chev panel truck.

Go to the HiPo Forum and look at the list at the top, also, just a reminder that since you have "crossed the line", future posts about your project should probably go in that forum.ðŸ‘ðŸ»ðŸ›

Very simple swap. | | | | | Joined: Sep 2014 Posts: 120 'Bolter | | 'Bolter Joined: Sep 2014 Posts: 120 | Thanks Marty...... I try to track one down.
Pulled the spring perches off of the old axle, so I'm ready to re-weld them
on a new axle.

Why try to cob up used ones? | | | | | Joined: Mar 2010 Posts: 10,275 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,275 | Were the perches you remove the ones from a torque tube? They won't work. They have that rubber bushing in them and will flex real bad if welded to an open drive rear end.
If your 3 speed auto has a final drive ratio of 1 to 1 (no overdrive), you may want to look for a 3.08 rear end for better highway RPM.

| | | | | Joined: Nov 2001 Posts: 1,517 'Bolter | | 'Bolter Joined: Nov 2001 Posts: 1,517 | I bought a pair of new spring perches off the shelf at my "small town, family owned" auto parts stores.
The radius fit the housing perrfectly,, just a matter of getting the width correct.
No "cobbling or rigging", just measure ten times, and get the width and pinion angle right, then measure it again. | | | | | Joined: Sep 2014 Posts: 120 'Bolter | | 'Bolter Joined: Sep 2014 Posts: 120 | Marty, Carl and Cletus:
I am going to buy new spring perches, weld on the flat plat and that will keep the diff from rotating under torque.
The old torque tube prevented that.
Thanks for the tips gentlemen !!! You guys are good !

The number 848 will be part of the casting number on the head itself. Bill was just fishing for leads. He posted the same notification in several forums. ðŸ›
