Wanted! RCM Hybrid Diffs - Cases Only or Drop ins

[sikeston34m]

I was using sales@rc-monster.com

I need the 4.3:1 ratio for my Outrunner Revo.

After I took a closer look, I see they do have the bare cases. So then I searched the forums on which gears to use to get the 4.3:1

I appears there is a compatibility issue with the pinion gear shaft being 8mm with no hole? What is the best solution to this problem?

This Pinion http://www3.towerhobbies.com/cgi-bin...?&I=LXJBM3&P=7

This Ring http://www3.towerhobbies.com/cgi-bin...?&I=LXJBM4&P=7

These together will give me the 4.3:1 ratio AND fit the RCM case?

I noticed something else here. http://www3.towerhobbies.com/cgi-bin...?&I=LXLGX2&P=7

The one looks like it might be compatible with the 10 tooth pinion gear for a 5:1 gear ratio. Will it work with the RCM case? If it does, I would rather go this way.
