Were all the pulleys made by ASP?

^ Yes

 

Ok thanks man...I think I'm going to have them make me a 6.0" with a 10 rib. I take it you had to make spacers for the blower bracket?

 

^ Yes space it out based on # of ribs, so in this case 3.56 mm / rib * 4 ribs = 35.6mm spacer (ASP will make spacers for you too).

Some more notes on running a 10-rib:

• The 6" 10-rib crank pulley may likely not fit as it'll interfere with the power-steering steering bolt.
• Note the offset water pump pulley I had made as well for additional margin. Without having an offset face, the belt will come close, but is probably OK.
• I had to get 10mm steering spacers (e.g. bump steer spacer) to move the rack up some to clear the pulley.
• You'll need a new idler pulley as well to match the 10-rib pulley. Make sure you account for the offsets and such on the idler considering it'll be wider
• Need to purchase a longer oil feed line for the blower. The stock SOS line happens to work, but you won't have any strain relief.
• You'll also need to notch the cross-frame member right under the blower as the oil return port will interfere. You'll need a 90-deg elbow to clear to route it out
• Before choosing any pulley combo, check to make sure a belt of proper length is available. The 10-rib belts dont come in incremental size options like the 6 or 8 rib do. It's very very limited.

PM me for more info, I don't want to take this thread off topic for the OP. In a nutshell, I would probably recommend going with a 8-rib as it's easier to work with.
