You have a very nice T5. Good gear ratios for an older truck! Yes, I believe the fin was cut off. They did a nice job too.
Trucks that get lowered
a lot might need to consider cutting the fin off for clearance.
That bar code should be a green and white sticker 13-52-145. That is the only number to use to identify the year and model of the T5. The numbers cast into the case, tail and lid are part numbers and can help you figure out what you have but are of no use to help identify the gearing.
There is a date casting mark on the lid, case and tail that tells you what year it was cast. That is useful sometimes if you are buying a T5 that someone has modified.
