15 years with the wrong belt routing

I put a small block in my Dart when I was 18 years old (2008). I am learning today that I’ve had my belt routine wrong from day one. My alternator belt goes from the crank to the alternator and back. Power steering belt goes from the crank to water pump to PS pump. I’m only finding out now because I am putting a new alternator on and decided I better double check my old work.

So would there be some big issues I need to look for from running it with this set up?

Usually the non a/c cars had the fan and alt and crank together. Then the p/s ran off the crank. Yours is the opposite it has been fine thus long so I would just leave it. Some also had a 2 groove top pulley that ran the p/s along with the w/p and crank. Kim
