see sig for vehicle details, I am changing from a 3.4 reichard pulley to a 3.3 reichard pulley. I used the belt that came with the kit when I changed from 3.6 to 3.4. That belt has at least 10k on it and occasionally slips now with the original belt tensioner (I'm replacing that too w/reichard auto tensioner). I am just concerned that the belt needs replacing anyway and it might be a little too long for the smaller pulley. If anybody has gone a similar route, please let me know if I need a different belt size or I should reorder the one that came with the kit. If you have it a size or part # would be helpful, even a brand if there is one better then the rest. Thanks in advance !
