I have a 1978 ish Monte Carlo dirt race car with a chevy 350, it didn't have a power steering pump, I bought a used Saginaw pump but it didn't have the mounting brackets, I bought a bracket set from JEGS and installed it to the pump and mounted it to the engine block, but now the pulley does not line up to the other pulleys, it looks like its about a 1/2 inch too far out. What is wrong?
