Cracker,

I am no authority by far on the Shelby Mustangs, but I don't think there was a letter designating one as a 500. Shelby got the regular Mustangs from Ford and then they did the work and added the Shelby numbers to it. That is the only sure way to authinticate one. You have to take the Shelby tag number and the Mustang number from Ford and send them to the SAAC as they have the records. Also they won't be in any sequence. For example maybe the Mustang from Ford with sequence # 50 may be #65 from Shelby. When one of the guys finished a Mustang they just took the next Shelby number in line and since some finished ahead of others that kept the sequence from being in order. Also makes it next to impossible to clone one and pass it of as an original.
