Meade DS2102 Telescope lost teeth for focusing in and out
It might be easiest to see if someone is selling one on Craig's list or ebay. You might be able to find one used where the telescope is OK, but the motorized drive is broken and replace the telescope.

You could try calling them and see if they will sell the part you need for the focuser. The focuser is called a rack and pinion focuser. From your description it is hard to know if it is the long linear gear on the draw-tube (the part that holds the eyepiece) or the gear on the shaft of the focusing knob. You will need to be able to describe that to them.
