I do confess guys, the real challenge was to find a thrustbearing which can fit the 2.6mm screw... Tamiya only sells 2mm...
So I look on the web, and after days of search (
), I finally manage to found a compatible one....

Then I found a shop carrying TOP parts and ordered them... A really great improvement for me, I'm quite disabled when it comes to build a godd smoothy differential...
Hope this helps!
