Go kart belts

What's the difference between a 203589 belt and the 203590 belt? Which one fits my mudhead? Both seem to pop up when I'm searching.

measure the distance between the crankshaft (center of the driver pulley) and the jackshaft (center of the driven pulley)
those two belts are of different size (length..uhm.. circumference )

203589 works for a center distance of 6 5/8 to 6 11/16 inches;
203590 is meant for a center distance of 7 1/8 to 7 3/16 inches;

for any other center to center distance,
just refer to this list:
