It will be the size of the current touchpad, sitting under a slightly  
depressed
portion of the front bezel.

The CL1A upper base assembly (keyboard, touchpad, white bezel around  
the two,
two side bumpers, and front bumper) should be available as a replacement
part.  It will it an existing (CL1) laptop perfectly.   I should be  
getting price quotes
in the next few days.

I haven't priced out a smaller subset yet, as it is necessary to  
replace the
keyboard/touchpad/bezel and an underlying PCB --- the only extra parts
in the upper base assy. are the bumpers.
