Rear Diff I.D.

[swanthog]

Hello.
I found that the rear 14-bolt diff in the '80 Stepside I'm building has been welded (Lincoln locker ) -- including the center pin! I removed the rear end from the truck and spent more than an hour grinding and pounding the center pin so that the carrier and pinion gears could be removed.
Here it is in the truck with the !&$%#^@#^$ welded gears:




I went to the local parts yard to find replacement gears and all the 14-bolts were already removed except this style of Diff :



Can someone please tell me what type of diff this is? It seems nobody wants these. All had the diff cover removed and all were left intact.

The one I am trying to replace is different. The pinion gears are visible and there is no bearing as seen in the photo (right,middle).


Thanks!
