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

Problems .. ?

You sold me a pile of mismatched parts it had no chance of working , I never yelled.

I have been nothing but understanding, you have received my emails no response


Don't you think it would be fair to at least attempt to soften the cost of repairs , maybe answer a email , act like you care about a customer .. that too much to expect ?
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.
