Not in the market myself but is this a decent deal?

Not bad at all. Being a 3/4 ton unit, it'll bolt right into a 1/2 ton too. Could be used in a 2 or 4wd too. I'd get him down to $225 though when I offered $200. Those things go in spirts. Sometimes you'll see 3 or 4 for sale at the same time, then it might be you don't see one for sale in a reasonable distance for weeks.
I've gotten one for FREE, answered a CL FREE ad needing it hauled off. 14b FF 3.73 drum to drum with springs and mega springs at that. It had some added.
Paid $100 for 1, 14b FF drum to drum 4.10 open diff which is what I preferred so I could easily add a Detroit Locker to it without having to swap carriers which also came with OEM C6P springs, one of which had been removed already.
I forget for positive now what I paid for it, but I'm wanting to say it was $150 I paid and I help pull it, for 1 out of a CUCV. 14b FF with 4.56's and Detroit Locker, also had disc brake conversion on it so it was disc to disc with calipers. Had a couple chipped teeth on the ring gear. I sold the carrier for $100, kept the Detroit Locker, it's going into the 4.10 unit I bought for $100 and the disc brakes are going on the 4.10 unit also.
