Question on parts value

The parts that you offer are very specialized and probably worth what you ask or more to the right buyer. Most folks here are working on cars that they drive, or a restored car that they show, for even occasional racers this is more than they need. You might look at advertising on a more racer oriented site to get more eyes on it. You might talk to folks at a Mopar oriented machine shop to help find a buyer and give them a finders fee or a percentage of what you sell for.
