Besides, HPA is doing this also, ~$2000 for the completely assembled Diff + 800 core charge. So there's no down time. Unless Wavetrac is offering a better pricing, I might just go with HPA.
HPA and Wavetrac are working together.

You buy your final drive unit from HPA, then send you a complete unit with the Wavetrac diff installed and charge you a $800 core fee. You spend a Saturday swapping it our in your car, send back your core, get your $800 refund. Sounds like for ~$2000 and a Saturday of labor you will have LSD in the 135 right?
