Hi all, Can anyone point me in the direction of a set of specs/drawings for the clamshells. 3d would be perfect. I assume that there are different sizes for different track widths?
Are there different slopes or arcs to them? I can`t tell if they are different or just mounted differently but the ones in the book (2nd edition) on page 184 bottom of the page look different/ better than most.

Thanks

Dale
