We rebuilt an engine for a customer back in 2011, and now the rear seal is starting to leak. I know two years on a seal is past the warranty and he drives the car almost daily, but it still shouldn't leak that early either. I want to make it right. It is a 302 automatic in a 68 convertible. Anyone know a good, reputable repair shop in the Charlotte, NC area that I could take it to? Thanks. - Dave
