I bought billetflow's 2.76 S/C Pulley with the 4 piece idler set with the new style bracket and plan on installing this weekend... I noticed that billetflow's website reccommends gatorback belt size 75.1" part #4080745 and then Cobrabob's website reccommends gatorback belt size 74.5" part #4080745 for the same application. Just wondering what size you guys found to be correct?
