1990 Dakota rear differential

I am having a hard time locating one.V-6, 2wd, octagon shaped cover, salvage. Anybody happen to have one sitting around? Any ideas? Put in a rebuilt engine about 2 years ago after almost 200,000 miles and then last
fall the rear end went.Sure would like to keep the thing going a little longer. TIA
