I'm assuming the two NSX techs work at Hendrick's Honda dealership in Charleston - correct? I live in Charleston and have a silver '91 with 6,600 miles that falls in the snap ring range and am thinking about talking to a tech about proactively fixing the snap ring issue. Of course, I hate to disturb anything on the car as it's completely original and there's always a chance that it doesn't have the snap ring issue just because it's in the range. Thanks
