I went through this once. I bought a new crank kit, put it in the engine and when I put the balancer on I found out the threads were stripped. Learned that lesson; check balancer threads before installing crank. I sure didn't want to take that crank out again. I managed to buy a bolt about 1/2" longer and it found some good threads to screw into. It outlasted the truck.
