I have not used these from March, but I had a set from Mopar some years ago. Everything lined up on mine. Do you know why your pulleys don't line up? Magnum engine with magnum timing cover and accessories should line up fine. If not stock, just cut a spacer out of flat stock of the thickness you need. Or have any fab shop near you make one, preferring water jet for speed. Balance should not be an issue.
