Unfortunately, the fender tag will tell you only what type transmission the car came with. If it's a 3 or 4 spd manual, then you'll know that the shifter was the right one for it. I don't think it will tell you if it's a 3 spd, whether it's on the tree or floor. Same with automatics, UNLESS you see the code for console (believe it's C16 and usually paired with bucket seats, C55). Gear ratio is not on the fender tag, it would be on the build sheet, if you have it. Build sheet if all together and legible will tell you everything the car came with, from tires, brakes, on up, etc. There is a good book called Mopar Broadcast Sheet decoder '69-'74 that breaks down each line and tells you what the codes mean. Handy book to have around.
