Thanks, they will for the rear ones for sure. I might still have a crossbar in my CupRacer bin..I'll check that later.
This is what I have from my M05 that I no longer use. The 2nd hole from the outside is perfectly spaced with the Rover Mini body pre-drilled holes as I found out.

I just need to make a bracket from the base of the damper stay to the chassis which shouldn't be too hard to do.
