I redid my cluster with LED's and an escalade gauge face when I swapped all my interior leds (radio, climate control, overhead, doors switches, etc) and it is very easy.
All the solder points on the motors are easily accessed and wouldn't take any special soldering skills. If you can do basic soldering you're golden. The most difficult time I had messing around in my cluster was getting the dang needles back exactly where I wanted them.
