if you can run a thin peice of cardboard (from a shreddies box) through both sides, then its good. It might also be a good idea to keep the cardboard wedged in thier while you bolt it up. When you start it up, if you hear a clicking noise, its installed wrong, or you got balancer/other troubles.
I took my car to Canadian Tire to get the crank sensor replaced, and the mechanic didint check for clearance, it made a clicking noise until the car broke down again (300 miles) because he didint tie strap the wires, and they got eaten by the belt monster.
