Took my Z to Datsun Dynamics back when I first got it. The minor work they did on my Z was decent but the prices were a bit steep. Dave used to come to the monthly club meets a couple years back but quit coming. Now Brian and Ryan occasionally show up. I guess you haven't heard of Bernie? He's your other option in this area - Alexandria, VA. As others have already done here, I'd recommend going that route, when and if he has the time. That would be the Bernie commenting in this thread, by the way.
