2003 Ford Ranger 2WD 3.0L V6 60k Flex fuel Serpentine belt

I don't want to sound dumb, but I am having a terrible time replacing my Serpentine belt after it broke while I was driving my truck. I can not get it on the last pulley, which every one I choose. The space to unwind the tensioner is so small I can only fit a normal 3/8 ratchet in there to unwind it instead of a breaker bar. I do plumbing on the side so I have the arm strength, but I'm thinking there must be a trick to it. I attached a picture of my routing. I have tried prying the belt on at the A/C compressor like the pictures dotted lines, I have also tried the pulley part of the tensioner assembly (middle top), as well as the alternator(top left), all with no luck. This is the Ford replacement part, I've tried all the after market stores parts which were almost an inch shorter, so I thought this one would be quick. I've replaced these belts on previous cars and never had this much trouble. Any advise would be most appreciated.
