What did you do to your truck today!

[mud.man.rj]

Well took my truck for a run yesterday but the big block was a bit cold and I almost stalled it so sidestepped the clutch a bit and turned at the same time while shooting out a tooth from the side spider gears right thu the rear cover so brought it home and gutted the rear diff. Now I need some info guy's in the know. I have a crappy 73 and up gov. lock posi unit, could put new spiders in but is it worth it, heard they are the "worst" GM diff. Will an Eaton or Auburn posi unit swap in place in the same diff housing (12 bolt). Here are a few pic's. Too much power and tire combo.Haha.





So anyone in the know on the swap.
