Im looking to find the original engine of my family's 69 365 GT NART SPYDER. It has been sitting in the garage for 30 years and we are now trying to sell it. Problem is we need the original engine. The Ferrari that has our engine in it is a 69-70 365 GTC serial number 12391. I hoping he would prefer to have his original engine back as well. Any help on how to obtain the owner's information would be greatly appreciated!
