Anyone out there possibly have (2) 5.80" Blower pulleys. I am running B&M 420's. I wanted to do a little testing with a smaller pulley. Used if fine. Or does anyone know of someone who has a collection of pulleys.????

i have a couple 16 rib top pullies....2 are splined and one is a keyed pulley

I have a 6 bolt pattern, they are B&M 420's other blowers also use the same bolt pattern. I assume you mean the pulleys you have slide onto a shaft with splines.?? If they are the 6 bolt type what size are they.???
