Unfortunately the parts for Mopars are a little more than for the mustang guys but hey its supply and demand.
Since i'm a buisness owner i look at things a little different than most other buyers.
I'm not bashing anybody but want to throw some things out there.

Is the part from a real company in the USA?
If he is he pays workmans comp and insuarance and more taxes.
Does he have a shop full of equipment and overhead?
Is he making a time tested part and will he be there in the future if i need him?
He is making a part for my not so popular chassis when he could be making them for the mustang crowd.

One last thing to keep in mind. Mopar owners are tough customers. Most put the price point before quality.
