Guys, got a roller secondary off an 06 Summit X with a DJ helix that I'm running on a ZX sled. I am wondering what you guys have for shims/spacers on the backside of the secondary and also wondering if you have one or two thrust washers between the sheaves? I received it with no shims/spacers nor did it have any thrust washers between sheaves. Stock belt for my sled fits into the secondary nicely with adjustment both ways still. I've tried looking at online parts diagram, but I don't know what to trust as there are different variables shown on the diagrams. Just want to make sure I don't eat something up metal on metal before running it. Thanks for any help/input you can provide.
