I own an MBX R2, I had no idea the 9.5 was compatable with MBX parts, the R2 is pretty much the same as the Pro minus the kickup chassis & alum brace. The LHS guy told me about getting a 9.5 chassis when I was picking up an LX chassis for kickup upgrade and I didn't know what he was talking about. I might get threaded shocks and maybe radio box from a 9.5 then.
