As I'm using a MRRC chassis with this body I won't be using the normal interior tray which is also the chassis of the car as all the parts clip or screw on to it, I could cut these off but there is not a lot of detail anyway. The body kit also came with a vac formed interior that fits over the original tray and has quite abit of detail but this is also no use for this build as it's for a rally car and has the co-driver moulded in. As it happens I have a vac form interior tray from Pendle's that is just about right, the rear seat back might be a little bit to far forward but other than that I just need to find a suitable drivers head.
