gtfour93, the 20 pinion in the link you provided is for a 48 pitch pinion. Unless I'm really wrong, these don't work in a Mini. The Mini uses a metric pinion which I was able to find at Tower, so Thanks for trying.
The Robinson pinion is well made and has the advantage of a stronger set screw hole and is less than half the cost. The Tamiya Flourine coated pinion lasts but eventually the set screw threads give up.
I am not 100% sure about the 48 pitch and metric info, but I'm sure there are a number of Mini gurus who can set us straight
Grandpa sounds like you found the correct pinion.
The M03/M05 uses .6 module pinions. This is the same as Robinson Racing's
Metric 48 pitch pinions found here (20T)

But the setscrew uses is a standard allen wrench and not a metric one.
