8 3/4 Price? Sure Grip Unit Price?

Ok, this housing is not all rusted. I painted it 25 yrs ago with Por 15. Now is the 400 to 600 with axles and brakes I assume.
BTW, I agree with this price inflation. Because of th base ridiculous prices, no younger guys are into the hobby, especially Mopars. These guys will die and their 1200 rear ends will be scrapped by their kids. Ha

Any idea on the Sure Grip Unit. No gears or carrier housing, just the unit.
