I need a new one as mine is tearing through seals. Anyone have a yoke or perhaps a driveshaft? Where could I order a yoke, napa doesn't sell them and the dealer stopped making them.

The dealer probably wanted more than an aftermarket shaft would have cost anyways. Cheapest route is to find another used shaft and swap the yoke. I'm sure someone has a bent or broken shaft kicking around. Are you sure the yoke is the problem or is the bushing in the tailstock of the trans worn allowing the shaft to move around too much?
