I did a rather difficult little trick involving making a change to where the springs actually connect to the hinge units (the pieces that have the sled grip hooks at the top). If I recall correctly, I had to notch the metal of the hinge units a bit. It was a real PITA to do because fiddling with those springs is always difficult.

Can't make pictures of it right now, my player is in the middle of a big synch. If there's enough interest, I'll do pictures tomorrow.
