I have no idea who entered the information that was used in the "Mustang Production Guide". I tend to avoid posting information on Internet sites. My car is definitely a fastback and it does not say 2+2. I have always called it a 2+2 for obviously no good reason.
I also posted the numbers incorrectly (sorry) for the door tag and fender. Door tag is 5F09K and the 5F07K is on the fender, motor and transmission. I guess if one is going to be correct, the door tag is the one you would want.
In your opinion, should I even care that the numbers on the Engine and Transmission do not match the Vehicle VIN? Would this effect the value?
All '65 Mustangs (GT or not) have the VIN stamped in 3 places (the door data plate, the driver's side fender apron (visible) and the passenger side fender apron (hidden by the fender - you'd need to remove the passenger fender for it to be visible). All 3 of the VINs in those locations should match. In the case of a K-code the VIN was also stamped into the engine block and the transmission in addition to the 3 places already mentioned. As a result, a K code '65 Mustang would have a matching VIN stamping in all 5 of those locations and they all should match.
Regarding the question of non-matching VINs impacting the value of the car it will complicate things. The fact that the 5 VINs are non-matching this will be a "red flag" and cause any future buyer to have concerns. However, given you are the original owner of the car you may be in a position to provide as much documentation as possible to offset this concerns.
Sample Documentation
- Any paperwork associated with the original purchase of the car (Original Dealer Invoice, Original "Owner's Warranty Card" that came with the car when new, Window Sticker)
- Any old pictures with you of the car when brand new
- Any invoices / service records detailing the maintenance of the car
However, for someone that wants a "true matching numbers" K-code car this will reduce the value of the car (regardless of any explanation of why the numbers do not match). I hope this helps.
