I plan to clean it up with the dremel and dust it with some paint.

I have made a some 1/8 scale plastic spur gear adapters similar to this. we didn't used to have the options we have now. I too discovered how hard it is to drill through these parts. What I discover is that you can dremel with a diamond bit in the spot you want to drill. Then you have to use bits designed for hardened steel. Available at most hardware stores. Drill press is a must. Buy at least few of them, they get dull or break and bounce off your forehead
so be sure to wear safety glasses. No joke I had one bounce off my forehead at very high velocity.
What I did was take a spur. I think it was an ofna 47t steel spur. I stuck the spur in a drill and spun it against a grinder wheel to remove the teeth as evenly as possible. then drilled the holes to hold on a ofna 51t plastic spur. It worked very well.
It looks very similar to what you have.
