Casio CS-55 Installation for PX-100

Hi,

Since I can't find one to buy, new or used, I'm goinf to have to build my own and am seeking some help.

In looking at all the pics I can find it seems there is no shelf extending from one side to the other.  Instead the two screws on each side of the PX-100 is attached to through the CS-55.  If so, does the CS-55 come with extra long replacement screws?

Along with the support board on the back, this should be very simple to build if I only go up just enough to reach the screw holes and not cover the connections on the left side since I have no tools to make a cut-out.

Thanks,

Selvan
