Well done a bit of searching and i'm finding it very hard to find any company that offers 4 door over fenders/rear quaters for a 4 door R32 so looks like it might have to be your way doug
i remeber seeing that the 2 door archs are way way out so no good using them for a mould , maybe the shape and the getting the wheel space cut out to suit the car... been told that the cef archs seem to be similar shape to an ps13 than a r32
