We have 2 6.9s. And 2 zf5 trans and tcases. Also have a couple 2wd zf5. What are they worth
I don't want to get too far off topic here, but I personally would buy the 4x4 ZF5s(make sure they are behind a diesel or 460 gasser) for $150-200 each; transfer cases aren't in as high demand, but I'd still pay $50-75 straight up, get a package deal if you can.
The 2wd zf5s, to me, are only worth as cores/parts for 4x4 ZF5s, but I'd probably still offer $100 and see.
6.9s, well, if they run and are complete(IP, lines etc)... $150-200. More if you need one.
7.3s in good shape, I'd go $200-250 maby? More if you need one.
Now, that's what /my/ prices are - that's what I will always offer on anything I find.
At those prices, if you weren't able to sell them yourself, I'd try to arrange a trip and buy them off you.
Will they sell them for that? Sometimes.
One local wrecking yard wanted like $300-500 for one 4x4 zf after looking at their computer, and I told them that was ridiculous.
The next wrecking yard got me a 4x4 ZF, transfer case, and an AOD automatic plus a few minor parts for $300?
The problem with prices is that if you have a real need, they can be worth quite a bit. But there aren't nearly as many people out there putting new transmissions in their rigs as there are old rigs at the JY, so you have a supply and demand situation here.
It also depends on the area.
