so i started to munch belts like mad...i noticed that my tensioner arm is spreading apart (moves the whole idler pully forward) causing the belt to hit edge of the idler pully......where can i get a replacment for the tensioner?

 

This is why I removed the springs in my stock tensioner and bolted the assembly together. Those springs in the stock setup gouge the soft aluminum and spread the assembly. I dont know how the SDCE works though.
