There is a 1-1/16 VDC master cylinder, from the 00-04 H6 VDC Outback. The only problem is that one of the ports is in a different place and it still requires the older style booster. Also the pushrod part seems different:

Nissans use an external check valve for the booster and they come with the cosworth intake manifolds. I think part 47478-04F03 will work.
As far as bleeding goes, you should really, really, really bench bleed the MC before installation.
