Rebound Valves...a must or?

Are the rocker cranks screwed into the gearbox top straight? Before I got the X11 front end, I found it was very easy to screw them in on an angle and it caused the problem you discribed.

The X10 prop willl fit the X11 as I've used an X11 one in my X10.

I was looking at a D4 diff last night and thinking it might fit the pred. It sounds like it might be a plan! Thanks Pro4 nut!
