Hi everyone,
Well, I finally had time this evening to carefully create a 3D CAD model of the 9500ci/ZR4 front shifter heads. Below is a link to a PDF which you can download, print out, and then cut out and tape together to create a paper model of a ZR4 front shifter. It should come in handy to check installation locations and to check where you can mount the shifters behind a grille without blocking it laser detection module if you merely wish to use the shifters in receive only mode.
I did a much more thorough examination of the front shifters today and confirmed my earlier remarks that the shifters must be mounted very level for best performance. The tolerance appears to be plus or minus 2 degrees for ideal performance.
