i agree with bb-dave.
Cuda' package cars had the fender script and fish emblem.
S cars with sport stripe only had the script.
S cars with stripe delete or accent stripe got the script and 340-383-s badges as well.
Base models got script and fish.
There is the oddball 340 non s car that got the 340-s badge as well even though it was not a formula-s car. They also had argent grills and tail panels.
The 383 could only be had in s or cuda' package so only the cuda' package got the fish.
