I installed a Smittybilt with the stereo bay in my 60 last week I made sure the rear seat would fold down and installed it "flush" with the rear seat lowered and slightly to the passenger's side to make a little more room for the hand brake. I wanted to make sure the cup holders and drinks would allow room for the shifter. My arm isn't completely on the padded section. I may move it up a little after I've driven more than a few miles. To mount it I drilled holes to mount it to the stock bracket. Niceguysanti had a god idea about using the extra plate for switches and gauges. I need to install a vhf/ham radio, cb, and a different stereo also. I'm not sure where everything is going yett.
