Are these Gatorbacks, and what size do I need for a 5% SC and 10% J/S Pulley, I read that a 10% Crank and 5% J/S took 43.5 is that the same as what I would need?
I have the MP kit with the same OD ratios and use a 40" belt, which you will need to clock the tensioner to run. You might just try the stock size belt and go from there. Green stripe belts are made by Gates.
