The VIN in the advert is off one character...there should be a "U" following the "2" which indicates this as a parchment interior car. I did pull out the registry and confirmed it is truly a "2U" car. Gorgeous.
Richstang has amazing records on these cars so I hope he chimes in. There were less the 40 Nightmist/Parchment GT500s and I believe #1724 is the last one built with these color if my research is correct. Not very many had automatic transmissions if I recall correctly.
The person advertising does not seem really well versed with Shelbys and so I would also urge you to get someone knowledgeable to go along and look it over. Best of luck and I hope this is a car that may work out for you.
Jeff - owner of #885, also a "2U" GT500.
Jeff, you give me way too much credit.
The only real source for the SAI (Shelby American) records is the '67 registrar and the OP wisely already contacted him.
That said, I continue to gather details from every '67 I can find.
The ad link does include a photo of the VIN plate with the '2U' indicating a SJ factory built Nightmist Blue car with parchment trim.
They show the SAI 'Vehicle Invoice' indicating the automatic car was shipped out of LAX with a radio and deluxe wheels (Magstars).
As many here know, it is wise to have the car inspected by a Shelby expert, so they can point out the good and the bad.
FYI; I didn't notice a fan shroud on this car.
