I just cut it out for the drive shaft to pass through. The cab mounts are just as close to the frame as the ones that hang off the outside of the rails. There is only about 12" from that one to the one I posted a picture of so I am not concerned with having the cross member connected in the middle. I would have to cut into the cab to make the cross member connect and have enough clearance for the drive shaft. If you are not going to run 24s at anytime, there would be room for connection, but I probably would still just cut it out and not worry about it.
