Registering a Race car in California

I just dealt with Cal CHP, nightmare in progress. They checked the VIN on the dash which does not match with the inner fender VIN (probably replaced in crash). The one on the drivers door is painted over, number maybe underneath but can't feel any dimples. Any VIN on frame of 68 Dart? They say if no two #'s match, then go to Cal. Air Resources Board for 2012 construction status which would initiate smog, etc. laws for new vehicles. Any HELP appreciated before I lose my mind.
