BluNblu, what do you think a B body 8 3/4 742 open rear end, complete from backing plate to backing plate is worth? I'm not going to use in the charger.
Funny enough, I just paid $400 for a complete 68-70 B body 8 3/4 backing plate to backing plate. Open 742 3rd member with 3.23’s, axles, 11x2.5” backing plates. It also came with a brand new set of billet housing ends from DoctorDiff, a brand new set of green bearings and a new set of perches. Previous owner was going to shorten it, and just the box of parts from DoctorDiff would be $155 new from him.
So, for just the complete B body rear and open 742 center I’d say $300 to $400 depending on condition and what gears are in it. I didn’t “need” the one I bought, I thought it was a good deal considering the gear ratio and all the extra new parts. And I’ve got a couple of 742 chunks so it’s nice to have a few chunks that match and can interchange parts. I’ve paid as much as $200 for a clean B-body 8 3/4 housing, and 742 open chunks are usually around $200. More if they have a more desirable gear ratio.
I think it’s more about buying a used cone style sure grip and not knowing how good it is. If you buy a clutch type, even if the clutches are hammered they can be replaced. If the cones are worn it’s a lot more work.
