removing a/c from 74 valiant

ok its a stock 318 with an a/c but its missing parts and i just want to remove it but im not sure how to get the belts right since the alt. belt wont clear the water pump. I have replaced alot of things on this car my self but this ones got me stumped. i can take pics tomorrow if needed since i know these 74 valiant/swingers are not common. anyone ever try this before?
