A couple of people to contact
Brett Zefting, A&P, based in the Dalles, 410-905-6712
Gary Brown, A&P, DAR, based at Independence 503-269-3907
Both of these guys helped me get my RV-7 back in the air following an engine replacement.
Not that in necessarily makes my recommendation any stronger, but I grew up in G'ville, SC...
Good luck.
