March serp belt pulleys with factory brackets

Anybody use March serp belt pulleys with factory accessory brackets?

I'm asking because I took my Duster to the drags the other day and tossed a belt at 7,000 rpm. I started looking at the March stuff since they have V belt pulleys but they told me they don't really offer any advantage over regular v belt pulleys.

The guy on the phone suggested going to a serp belt set up using the factory style alternator bracket as the tensioner. Anyone do this? Just looking to prevent tossing the belt next time out.

Pics are good if you have 'em.
