That first link is for the evap motor for a CS-96 round top, this motor is the right one for you:
http://www.fun-tronicsllc.com/index.php?crn=306&rn=610&action=show_detailIts a pretty easy replacement, there are 4 screws to take off, two in the front that hold the wire harness, and two in the back that hold the top of the evaporator lid on. Just take out the bottom few shelves and you can get to the motor without taking the whole compressor out.
The only problem is the motor replacement doesn't come with the plug that goes into the front of the evaporator, so you'll have to cut and reuse the plug, or just wire the motor straight into the junction box on the right hand side.
