I'm sorry but this makes no sense to me as what you are referring to. As far as mounting the engine to the chassis it is simple especially using the Mp9 engine mount. The MP9 engine mount makes it a breeze to adjust the angle and to be able to align to engine just right.
BTW are you using the same M2C6074 clutch kit on your Kyosho? I noticed that they make a kit specifically for the Kyosho MP9 series although I think the only main difference is the size of the flywheel being slightly smaller for the Kyosho...although I am having no issues with the bigger flywheel sticking out of the bottom so I'd say this kit is good to go.

Edit: Oh okay I think I know what you are saying...using shims behind the front. I guess I got lucky because this thing lines up right stab in the middle so it looks good.
I could probably get away with this clutch bell but will still order one of the others mentioned simply because I like the idea of having a slightly longer clutch bell to sit over the clutch shoes better...although these still just do cover them but the clutch shoes can be seen if I tilt the engine way to the side. I could just go ahead and order my Werks fuel (waiting to get paid in a few days) and try this setup out anyway. If it is slipping I think I would know even while breaking it in.
Thanks.

Here is a picture of how the clutchbell is lined up with the center diff...just bear in mind that I do not have the engine locked down just yet but I'd say this is a pretty decent fit...Inknow these pictures are not the best and why does this new IPhone 4S make everything look dirty??
