And does anyone know if the OBX racing helical front LSD that fits the 02- 05 wrx will function correctly in my 07 wrx case?

Before you buy any of these, do some research on the Legacy GT gears that come standard on Legacy GT's.

In fact, since you have a push-style clutch, I'm pretty sure all you need is a WRX specific front diff a speedo gear to install a Legacy GT transmission in your car.

The OBX one you mentioned would fit the bill for either a re-build or the Legacy GT transmission.
