The cutout I put in mine is similar to the one RS and SS built into the ears they were making, which Lee said was accurate to the original. I thought I saw a picture once, but not sure. I put mine in before even knowing, I was torn between going micro-switch or mercury switch for a while. I asked for advice here quite a while back, and the majority was saying micro-switch. So I cut a spot out for the microswitch. The fact that it was so similar to the ones RS and SS put out, and possibly the original, is pure coincidence
It was kind of cool when I saw them come out, I was like awesome, maybe I stumbled accurate accidentally
Anyways, these aluminum ears are frickin sweet:love And aluminum hollow stalk
Man, wish I had the $$ right now:cheers
