Let us know what you find. Keeping in mind over the years replacement/crash parts may have been put on which could have other numbers or NO numbers if a Dealer/NOS piece.. Radiator supports were common pieces to be replaced therefore losing those numbers. Even trunk gutters were cut out and replaced due to rust with-out any thought top the numbers under the gasket. It doesn't mean someone tried to pull a fast one just trying to replace parts BEFORE these cars were ever scrutinized.
