Am I just SOL?

Not me, I dont care how convenient or cheap they are. Matter of fact I have one out of a ranger with 3:73, but not in any of my mopars. This ain’t Cuba yet.

My local junkyard sells 9 1/4 truck axles for $350.
I agree. I have nothing against a Ford Trac loc but the Mopar Sure grip is a tougher unit IMO.
