They will be CRUSHING all mopars in their inventory

So then if they really want to keep the hobby alive, they'll sell parts at scrap rate since its just going to be crushed anyway?

They've got a plum crazy 70 dart that looks restorable for crying out loud.

Good luck with that. I have been down this road with salvage yards before, a couple times.
I needed a roof rail trim piece off a 57 Plymouth (1985), and they wanted $100 each, for them. They were getting ready to smash them all and I made them an offer of $50 and they said they would rather smash them.
