How much rib material do you have to take off for the magnum powers 10 rib 5% supercharger pulley. 5/8 or 3/8 can't remember?

if u mean a 12 rib bet to a 10 rib, just take off 2 from what ever side. Thats what i did with my 15% 10 rib setup

I think he means the ribs on the snout. I just took off the width of my file. You can take a little off at a time and see if the pulley fits. If it doesn't take some more.
