Putting the quartz clock conversion in really isn't all that hard. I think the kit cost $65 a few years ago and it came with adequate instructions. It only is the movement, so if you need the face redone, there are the decals or the restoration places. If you're brave enough to pull the rallye dash out, the clock would be a piece of cake.
On cleaning the lens: a soldering pencil can be used to melt and ease off the plastic tangs that hold on the metal around the fuel and temp guages. Try to pile up the plastic in the center of each protrusion so you have something to melt back down to put it together again. Meguires plastic polish worked nicely on ours.
