Dino 246 blueprint needed

I am trying to do a 3D model of the 246GT (or GTS) and cannot find any images of the 246 body. There are a couple out there of the 206 but even the official manuals of the 246 have slightly altered 206 drawings in them. Ferrari seem to have got lazy in their illustrations and just reused 206 drawings with new wheels and altered text. As soon as you superimpose them in Photoshop you can see that it really isn't a 246 with 2340 wheelbase at all. Does anyone know, or can post, a 246 blueprint?
