I bent the line a little closer to the case (block of wood and a hammer YMMV) and the result was a small gap (1mm) between the alternator-line-case. 40 hrs with regular inspections indicate that it is working. Thankfully, the parts don't move that much.
The 15358 belt is a good idea too.
Edit 8-15-18 - I looked at mine again. Note (below) the adjustment slot has the bolt near the end. I used the standard belt, as the adjustment range might not accommodate much extra length.
Let us know how yours works out.
