Not on fender tag. Unless you have the build sheet or window sticker you can't tell for sure if you got that ratio.
3.55 was standard and 3.91 was optional on T/As and AARs.
Sorry to hijack, but on a similar subject, my T/A is a 3.91 car, I had a repro ratio tag, but it doesn't look like the resto shop installed it on my rear, nor gave me back my tag. I have to buy another, but which stud on the mounting does this tag go on?
