Mike, isn't that the second 14mm head that's stuck a p/b on ya? Randy had his and it blew up on the test stand, never even made it to the truck. He's about to try number 2 as well... but I'm thinking he should return it, they just don't seem to be holding up. Sorry to hear about that, let us know if you get a good one.
Caleb, take care of Vicki, she is way more important than a truck event, give her our best wishes for a speedy recovery.
