I've been working on picking up some parts for a 1970 Mach 1, and I've been finding often that the same part (or seemingly the same) sometimes has different OEM part numbers when you find them online, and it's hard to tell which exact part number my car was supposed to have. In some cases I can look at the car and see what it currently has, but in other cases where the original part has been replaced, I don't have that option.
Is there database online somewhere where I can search for parts for my car (by VIN, for example) to make sure that I'm buying the correct ones? The main Ford parts website only goes back to 1980, apparently. You can search farther back but nothing comes up other than a section for caps.
Thanks!
