I've got a wavetrac ready to go in. Not sure how I'm going to get it installed now.... if I want to make sure its done right I might have to end up shipping the whole pumpkin out to Metric Mechanic or DiffsOnline... was really hoping there would be a shop somewhere in michigan that I could find to install it, damn.
