Robert, I have tried numerious combinations of the bits and have not been sucessful at fiting the alternator and its idle wheel. The upper bolt for the alternator is the wrong dianmeter (too small) for the head attachment, and the proper size bolt is too big to fit through the attachment point on the alternator. The support bracket for the idel wheel has holes that are too small for two of the three bolts (one on water pump, and the shaft for the wheel. What am I doing wrong?
