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

I contacted the company in question once. Was looking for a forward shift manual valve body. He told me those were for sissies and real men used reversed pattern. I ended up buying one elsewhere since he didn't seem to want to sell me one. Sorry for your misfortunate with them, but if they took me for $4500 they'd be fixing the issues or refunding my $$.
