Re: 2004 40th Anniv conv.
Yah in 04 all the v6's/GT's/Mach 1's were 40th Anniversary cars...they all wore the 40th badges on the fenders. There were limited production cars that had the special anniversary package...wheel accents, stripes, painted cobra mirrors, larger headrests (Mach 1/GT), and the small 40th plaque on the shifter bezel next to the cigarette lighter. Everything was cosmetic, no performance upgrades or changes.
If your car has those things and is either crimson red, white or black with the stripes then the car is a special anniversary. If it doesn't have those things then you have a 40th anniversary car.
The 35th anniversary in 99 was the same way. All the regular v6's/GT's had the 35th badges on the fenders and the special 35th GT's were certain colors with certain cosmetic options.
