On Robinsonracing website it shows both .8 and 1.0 module pinions. What are the difference? and are they both 32pitch?
Thanks!

Module is a metric way of nominating the pitch, similar to the way there are metric and imperial bolts. They dont interchange with each other although some may appear pretty simmilar.
So you need to find a 32 pitch pinion, unless you want to change your spur aswell.
Anyway, you could always type a search into Google!!!
