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

Give it up dude. Your builder had to call him to find out whats going on with it. There's more to this than we will ever know.
please forgive me if I don't use that advice , I am now out $7000 and the nightmare isn't over, I know few that can afford a hit like that and just go down without a fight .. I surely can't I will work to spread the word and use any legal channels available to me till I exhaust all avenues
