You shouldn't need to. Without knowing exactly what dimensions the OEM drivers are, you could most likely fit (almost) any 6" driver and even probably a 6.5" driver. At a guess though, they will probably be 5.25" coaxials, possibly 6".
You will need to make a baffle out of mdf to mount to the door, and the speaker to the baffle to make them fit. There's plenty of info and pics on here of what I am talking about.
