What emblems go on these fenders

Rocky is correct... What about the drivers side ? Bottom holes are too far apart for a "S" badge it appears ? Maybe a 383 fender ?

They only put 383 badges on the fenders for the 67's. 67 did not put the engine size in the hood inserts, just lines/ribs.

In 68 they used the round Formula S badge and put the engine size in the hood inserts. and the hood inserts were smooth, without the ribs.

An original 318 car in 68 got the rectangular V-8 emblem under the Barracuda script.
