i was looking to have mill work for the Grip Style 2 cutouts added to a 7" double female extension. I was hoping to also have the cut outs made on this for an Activation box 5. Does anyone know if there is room enough on a 7" extension for both of these? When i try to mock them up on the MHS Builder, it looks like it might work. Am I good to go, or do i need to go up to an 8" extension?
