maybe walk through your local salvage yard to find something to suit your personal preference.as far as putting it under the dash i think your biggest challenges would be on actually mounting it(probably have to tack weld a bracket to the inner structure of your stang,drill a hole in your firewall for the cable to come through,then find the correct length of e brake cable(im sure there would be custom set ups available somewhere).as far as leaving it off...you might want to think about that..say you were to get in an accident because your brakes failed.and your insurance company finds out that you deleted your e-brake,you could have your claimed denied(unsafe car)...insurance companies are just itching to find ways to screw you over.

post some pics when you are done
