Here's a better question - if you know absolutely nothing about them and haven't a clue as to whether or not they're any good why did you buy them?
Do you often make it a habit of buying gear you are clueless about?
I've got some stuff to sell you if so...
Off Topic ~ Is that your truck in your avatar? I saw a red one built like that at a dealership in Corsicana, TX once and assumed it was a one-off since I had never seen one before or heard of a 6-door F-series prior to that.
