This Radar is the latest version and is what is going on my replica torso. It is correctly sized to fit the replica collar and Torso. (the club collar is 4″ thick the new size is 3.625″ thick (and a little narrower). As you can see with this picture, the clutch pack has a tapered top. A top view shows a milled out key area for the bubble lifter (never mind the slight dent off to the right of the key – it was a mistake but it will be covered up with the bubble lifter boot cover so it doesn’t matter. Also note the 2nd half of the radar has upper and lower base plates where the ears are inserted.
And of course here is the Bubble lifter tube with the key inserted. I have included the drawing
so you can assemble your own.
