Is it possible to use 2006 sti or wrx doorcards on a 2003 WRX, as a few interiors pop up for sale in almost new condition, I know some of the switches are different, but can the ones from the 2003 door cards be used, or do you have to buy all new ones,

 

tricky one

try and get one door card with switch gear, maybe from a breakers? To have a play with, possibly slim chance on finding a wrecked car so new - but worth a look
