? was the truck modified before you bought it?
I dont know a thing, but I do know that those that own Powerstrokers and those that make modifications are all about listing every last thing they do. I would assume that whoever owned it prior to you would of made each one of them known.
But I guess if it was bought at a dealership they wouldnt of probably had a clue.... I am sure that once Stroker X and Kornfed get back from NC (they got to take their time) they will have a good Idea of who or where, or you could just meet up with us all at our next meet and greet - we will be having on in December - Not sure if we will get one in here in November.
