    NOTE: All Belts are 4-rib, NAPA Belts run smaller than all other belts, so sizes will need to be increased(10-20mm) from the listed sizes below!

    You're gonna need a 640mm belt from the blower to the alternator(stepper) and a 820mm-840mm belt for the alternator to crank.

    Stock Belt Sizes
    AC = 31" = 790mm
    PS = 36.5" = 930mm
    Alt. = 33" = 835mm

    6psi JRSC Belt Sizes
    AC = 31" = 790mm
    PS = 36.5" = 930mm
    Alt. = 31.5" = 800mm
    Blower = 24.5" = 620mm

    9psi Stepper
    AC = 31" = 790mm
    PS = 36.5" = 930mm
    Alt. = 31.5" = 800mm
    Blower = 640mm

    10psi JRSC with CRV Pulley Belt Sizes
    AC = ????
    PS = 900mm = 35.5?
    Alt. = 850mm = 33.5?
    Blower = 24.5" = 620mm

    8psi JRSC with Blower Pulley Belt Sizes
    AC = 31" = 790mm
    PS = 36.5" = 930mm
    Alt. = 31.5" = 800mm
    Blower = 23.4"-24" = 595mm-610mm

    We need an FAQ section, and that chart for belt sizes definitely needs put in it.
