273 Commando - UTG

My 1st 1965 Formula S I looked at in 1974 and eventually bought about 1976 had a 4sp and 8 3/4 - I still have the fender tag along with a lot of the parts from it - it had the side swiped as it sat out on the street. My current 1965 S 4 sp is a Feb build with a 7 1/4 posi. Parted a 1966 auto S car with a 8 3/4 but since it had a 340 in it not sure if it was orginal - that fender tag is somewhere - wounder if the tag would have a code ?
