Anyone local to me capable of correcting errors on a 904 race build

well , sadly talking to him is more than difficult. he just told me I needed to calm down and hung up .. lol , I assure you I was just trying to ask a few questions.

I just called a guy in Minneapolis, he confirmed some of my concerns in a quick phone call and funny thing is he has another 904 from same builder with problems he is working on the guy didn't want to send it back to the builder either for same reasons as me
