Sam01contact - why would you want to make the cut on the rear of the body like that?? there are several compound curves that you will have to match. Also I see it will require a lot of putty to match smoothly?? Jedi made the cut where I think it is most logical. Also what in the "nylon" method?? never heard of that technique can you explain it? I do like your changes to the belly pans and diffusers. Thanks again for sharing all your work - John
