Doubtful but possible. As with all small manufacturers there is some leeway on how each car was assembled. Even a poll won't answer the question since we don't know the location of 100% of the cars - all it could do is get us the latest known example. If the latest known is under 1,500 it would bolster your statement if it's over 1,500 it would indicate later cars do exist with the hump.
If the car in question (a 66 late Shelby not a carry-over) were built I have not seen or heard of any of them being built with a 5R Ford VIN. Pretty sure that if there was one or more Howard would know it since they have all the Ford VINs and it would finding would have been written about or shared after all these decades. That would be a requirement if it were to have the early floor pan with the pass through depression in the floor.
If it were on a car VINed with 6R your example would need to have be
1- A 66 Mustang built at San Jose would have to have had a "left over" early style floor from 65 production ten or so months before that was discovered at the plant or the supplying stamping plant
2- That same car would have had to be chosen to be built into a K code using that floor but it would have more likely, just based on percentages, more likely it to have been installed in an A, C or T code
3- The floor would have also needed to by random chance be installed on a fastback body. Again much more likely, based on percentages of body types built, much more chance that it would end up installed on a coupe body
4- In addition that 66 body with the 65 floor would have had been chosen or designated as one being sold to convert to a 66 Shelby rather than a K code Mustangs fastback.
Guess it would be time to by a lottery ticket
I'll leave it to someone else to figure out what the probabilities are of all those things working in a row.
