aluminum bell, or lakewood? i could see it being EASIER with a lakewood, especially once you tacked a wire retainer to it in the inside. with an aluminum, you could drill and tap a retainer. or drill a small hole through the block, cut the wires, and solder them back together after its fed through. would hate to do it that way, though, as youd have to pull the trans and clutch to chenge the sensor for the crank position.
