So they were the same wheels just with the painted inserts? I couldn't remember what the 94-95 wheels looked like. Now that you mention it I kinda remember that though.
94-97 Cobra rims are physically all the same. Difference is finish really.
94-95 rims, polished finish
96-97 rims, polished finish, painted inserts
Center caps are the same, and in common with a rim used on the 2000-2004 V6 Mustang.
The 1994 Cobra Indy 500 pace car actually uses the 96-97 Cobra rim with the painted inserts. This is actually one of those Mustang trivia things that not many people know
