The complete kit price looks like it will be $160 plus shipping.

The kit will have the following:
1ea. Custom made 6061 aluminum spacer
1ea. 12mmx1.75x50mm grade 8 bolt
1ea. 12mm washer
1ea. K081088HD belt modified to 7 rib
1ea. 54mm idler pulley

Please don't send in any orders just yet. I'm pretty much swamped until June with other work commitments (I'm in high demand this time of the year).
