I have the automatic, but this may give you another idea. I'm going to bend and form a small piece of aluminum to conform to the top of the transmission hump. I'll fasten it to the carpet with large pieces of velcro tape. When the cup holder is open, the piece of aluminum will be underneath it, out of the way. On the left -- driver's -- side of the hump I'm going to heli-arc the brackets for the CB radio, which will stand up straight, with its controls pointed towards the headliner, and it will be oriented fore-and-aft, so the bottom side of the CB radio will be next to my right leg, with a clearance of about 3" or so. At the same time I weld the brackets for the CB radio, there is also enough room for brackets for my small Yaesu 2m-440 and an aluminum ring that will hold a 1-qt Stanley thermos -- and the cup holder will still open and close. With everything mounted to the aluminum plate, I can remove it all if I want by closing the cup holder, disconnecting the antenna and power wires, and lifting on the plate until the velco comes loose from the carpet (of course, so can anyone else who breaks into the truck if I've left the radios in place, but that's the downside of not having enough space to get these accessories mounted).
