Chris - I can't remember if you previously posted pictures of your engine, but couldn't find any so hard to say on belt fit without a visual of your pulleys to consider belt width/depth, etc.
It sounds like it will live happier with the 15430 and/or 15425 (I think you typed 15325?) which are generally 0.44" and 0.4375" width respectively.
The only remaining difference between the 15430 (43.0" overall length) and the 15425 (42.5" overall length) result in your alternator standing up a little taller and closer to the engine center line using the slightly shorter belt.
I recall John posting about searching for the right length belt as I think his alternator leaned too far outboard.
