One more thing to cross of my "to do list"
This works great. No heat treat required. It really does not take any pressure on the sides just use the thumb screw to keep it from moving.
But if your pulling my solid State relays, you must disconnect the battery or you will blow the relay and maybe melt your harness. The fan fail should be OK with batter and the dome light if you pull the fuse for it.
I've just about run out of most of my circuit boards so I will move those bottom exposed pads in 0.025" just in case.
