my uncle has a 66 mustang that i have been driving this summer and i was investigating the data plate and some of the numbers along with the VIN and i cannot find what 2 codes mean.
i was also thinking about getting a marti report on it also since its original with 85,000 miles (and its for sale too)

the 2 codes:

DSO - 17

Trim - 36

all the rest i found. anyone interested in picts PM me. (note: the car is still original so its not "perfect" or anything like that. PM for details if interested.

 

DSO 17 is Washington, and Trim 36 is Black Bench Interior

 

Ford didn't keep records for 1966 so no Martin report. I think they start in 1967.

 

Spellcheck, grrr. Marti
