Numbers Matching - What it means to you...
Second post - I think I am going to like it here....
I am sure that has been covered here before, so administrator - feel free to redirect me....
I would love to get a few opinions on what "Numbers Matching" means to you?
Here are the three definitions that I have heard and would love some clarification on this (tweak, add-to, delete, disagree/agree with these three).
Defintion #1 = All parts and peices on the car are original to the day the car rolled off the line. Nothing has been replaced or upgraded. The car can be a restored vehicle, but the engine, trans., rear end, intake, heads, carbs, guages, coloring (anything that makes the car unique) must be original to the car. Paint, interior, glass, chrome, etc can be replacements, but they need to be accurate to the nth degree.
Definition #2 = The car is "factory correct", but some of the original "core" (outside of what is VIN specific) equipment has been replaced with factory-made components that are date coded earlier (how much earlier is acceptable?) than the production date of the car. All options on the car are present and none have been added/removed/replaced. A 4bbl car is a 4 bbl car, a 4 speed is a 4 speed, etc. The engine could have been replaced (or trans, or rear end, etc), but the replacement component cooresponds to a part that could have been "grabbed" during the production of the vehicle. This gets gray when you are talking about certain components being VIN specific and others (like pre-VIN blocks not being). This definition would state that VIN specific parts need to obviously be present in order to be "numbers matching". In addition to VIN other codes are required to be present (such as an engine code being present that matches the car in is residing in).
Definition #3 = The car has been rebuilt over time (either through maintenance or restoration or both) with components that are of the correct model year (date codes could be slightly behind/after production date), components used could add/delete options that were not present on the original build sheet. An example of this would be a factory in-dash tach on the build sheet and a clock on the restored ride. Or a tri-power convert car that has a date coded intake that matches up with the car (either pre or post production, but within reason). Obviously under this definition there is some freedom in "what dealers migh thave done back in the day".
There are obviously differing views on what is meant by "numbers matching", "factory correct", and "original". And there are obvously a whole host of individual defintitions out there.
I would love to hear some of them.
