There are several older Mopar guys here in town who have hoarded up a lot of cars and parts. Most of it isn't for sale unless they stand to make substantial money on it. The high prices will come down when this age group leaves the hobby as the number of people after this stuff in the following generations is way less + they have less money overall. It will sell for less an/or their family members will haul whatever doesn't sell to the scrap collector someday.

Having also owned old GM and Ford cars I will say the local Mopar guys are the worst when it comes to hoarding up stuff and expecting to make large money on even the smallest parts.
