semi-svelte accessory belt

I wanted to work out accessories mounting and the belt.  The factory mustang had a smog pump under the alternator and may or may not have air conditioning which affects belt length and routing.  The previous owner removed the smog pump and had the belt routed in a weird way that only contacted the crank shaft pulley for less than 90°.  I didn't feel good about that routing so I decided to try the original factory positions for everything.  Supposedly the 73" belt should work... but it doesn't reach at all.  So I am using the 82" belt from the focus.  I had to tilt the the alternator out a bit to pick up the slack.  So I made a bracket (you can see it at the top)

 You can see that this routing is no good since the tensioner makes the belt contact itself.  No matter how tight I make my bracket, I can't stop this contact.  So I moved the tensioner back to the custom location the previous owner used.  This puts the non grooved tensioner pulley on the grooved side of the belt:

If you look closely you can see the idle pulley on the tensioner is different in the lower picture.  I used the pulley from the focus tensioner.  It fit, but because the bolt was smaller, I had to drill out the retaining washer. 

Also, found out that the pulley bolt on the 302 is reverse thread.  I hope that doesn't mean it will spin off now that I flipped sides of the belt.  I suspect the reverse thread was only so that when you wind the tensioner open with the breaker bar you don't loosen the bolt.

Here is a close up of the alternator bracket I had to make:
