raikkonen as coulthard prob with averygpfan's wad and performance

Ive recently installed averygpfan's car.wad and performance which i think is great, but the only problem is that raikkonen is shown in game as being in the number 4 car which is correct but has the coulthard blue with white cross helmet. Also coulthard the number 3 car ,which is correct, has Raikkonen's helmet!!

Is this a known problem with this car.wad and performance file?
Coz at the moment the only way around it seems to be to make raikkonen as the number 3 car and coulthard as number4 which unfortunatly is the wrong way around!

Please help

Cheers BYF
