Since it seems I'll keep getting questions about the PG, I'll address why I went with it.
I had my decision narrowed to the Torsen or the PG, with the Quaife being far too expensive for my needs.
I really just wanted additional straight-line traction at the drag strip.
I contacted PG and requested a discount if I provide a how-to, which I would have done anyway if I ended up liking the unit.
They sent me the PG unit free of charge, including the stronger spring kit.
That made the decision pretty easy.
This is also why I welded the dowel pin. If the PG doesn't work out I have no intentions of rebuilding that diff again.
I spoke with the folks at PG over the phone, and they are quite confident in their product.
That being said, I'd like to keep this thread as a how-to and not debate of which brand is better.
It will probably be a couple months before I can provide a decent review on all the parts used in this how-to.
