I'm pretty sure that'll be a custom fab deal.

NOOO!! lol anyone have any experience with the Unorthodox aluminum crank pulley? anything good? bad?

unorthodox makes good products but with any full metal crank pulley you may decrease the life of your main bearings. The loss of the harmonic balancer (rubber around the crank pulley) causes vibration on the crank. I would consider having a machine shop cut the non needed pulleys off the stock one and then have it balanced. One of my friends did this and it seems to work just fine (wont be as light as an unorthodox but it would be safer and cheaper).
