thank you buddy :beer:
hey hey this is about me not sleeperstatus !! J.k thanks for the help guys !!
I'll confirm the 77" belt, that's what I used with a 2.75/4lb combo with the stock alt pulley and a 100mm aux idler. I went through several belts trying to find the right one when I swapped the alt pulley. With the 2.75/4lb, 3.2" alt pulley, and only the 100mm aux idler I squeezed a 78.5" belt on the car. Currently with the 2.65/4lb combo, 3.2" alt pulley, and all 4 idlers I had to jump to a 79" belt.
