Well, you were right.

I would post pics of what it looks like, but I don't have my mandatory 9 posts yet.

In any event, I see that ordering a stock open diff from marlin is crazy expensive.

I am running 33's all the way around, and as far as I know, the rear end is the stock 93 4-runner.

Can you recommend a part (or kit) as well as any other "good to have's" to get this thing back on the road like QUICK?

It's D.O.A, with the front axle laying on the ground and the carrier in the solvent tank and the auto hobby shop on Marine Corps Base Quantico is charging me $50 a day for it to sit there while I scratch my head.
