Bodies for mbx-6, non eco if it makes a difference

Hey Magman,
It's been a while, but I have been slowly getting my MBX6 into shape to run. I am like you I have the nitro with Mike's conversion. I have tried both the proline shift and bulldog, but to me there is no room on the sides. Even though everything will fit, I am concerned about air flow. So to me taking the Mugen Eco body and cutting a couple on millimeters off the rear has been the best option. I can't speak for the J Concept stuff as I haven't tried them. Hope this helps.
