I was checking out their web site and noticed that they have the Trade Mark rights to Fenton headers for flat head Fords, but not six cyl chevys. My only question is did they try to buy the rights to produce the chevys and couldn't reach an agreement or why would they go to Patrick's and tell them they were going to start selling them. That sounds a little strange, would you call up a bank and tell them you were going to be in tomorrow to rob them. I also noticed that they have discontinued the sale of chevy fentons for now. There is only a price difference of $8.00 if Patricks personal service isn't worth eight bucks, I don't know what to tell you.
