So the bottom of the shocks I want for my Radio Shack Golden Arrow have too small of a hole on the bottom and a bigger hole on the top. Here are the shocks I want to use on the rear of the Golden Arrow:

As you can see, theres a bigger hole at the top of the shock. Theres a thicker bolt to hold the shock in place on the Golden Arrow at the bottom end of it. I was hoping to either turn the shock upside down or drill out a bigger hole on the bottom? Would it hurt anything to mount it upside down?

Or do they make shocks this length that have bigger holes on each end?

What pitch pinion and how many teeth does the stock Golden Arrow have?

I don't own the Radioshack Golden Arrow but I have the Nikko Thunderbolt with 540 motor. Golden Arrow is a "copy" of Thunderbolt / Bison / Rhino because Radioshack distributed and rebranded many Nikko cars.

Thunderbolt´s Pinion is 17T and 0.8 metric module

Interesting about the Nikko gears being 0.8P. I have in my GA a spur gear from a Traxxas Cat and the parts manual lists a 32P for the pinion with an option for a bigger gear. I have a lot of time on the GA with the Cat gear with no signs of wear.

These are the equivalences between metric (Europe/Japan) and imperial (USA) gears. It is essential to know this if you are looking gears for toy / hobby RC cars .

0,8 metric is compatible with 32 d.p. and 0,4 metric is compatible with 64 d.p.
0,5 or 0.6 metric is NOT compatible with 48 d.p.
