i dont have a pic of it done and the car is assembled... but u see on the pic in front of the brake seat, the diff cup modded cup for the prop shaft...? aye, all i did was superglue the cup on and then grind a flat each side - just to give it a bit more meat for the disc to grab onto.

works a treat with the os18 and a high torque servo behind it... so far at least...
