Inside for both side of the arm, 1 side have 3 holes and the other side have 2. Looking at comments in "Kyosho Electric World" FB group, one side should be 17.8mm and the other side is around 19.5mm.

Hello friends,

Do you know if Kyosho (or other brand) have a CVD-Rebuild kit in order to replace the internal screws of the CVD?? Something similar to this:

Man, 1st time on the track didn't go so well. I had zero traction out back and after trying to adjust the slipper things went south. The buggy would be ok for about half a lap and just slip out and almost go nowhere. Well after pulling the slipper apart and doing some online research I found out it has the Schelle Racing Nova slipper. I am a noob and all about simplicity for now, should I just swap back to the stocker? I have never even dealt with a slipper being I ran 4x4 short course and 1/5th gassers.

Kinda takin a shot in the dark here, anyone on here have any connection with AvidRC? I've been checking for the AvidRC axles for the past couple months and they never have them in stock. I emailed them but no response. Just hoping they will be getting more in.

Does anyone know if the one piece alum big bore shock caps are the size of the old long plastic caps or are they the same size as the old short plastic caps?
