well as you can see from the pic its 40mm from the diff mount to the lip on the buggy and mikes mount is 48mm from the bolt center to the edge, so he is going to cut a radius on the bottom corner like it has on top for me.
And a few more pics:-

I cleaned up up my metalwork and refitted it.

Fitted the wing

And put on the decals
Squee, what size alen key do the larger alen bolts take? (the wing bolts and shock mount bots etc) I gotta go get one.
