Small update for anyone who cares..
Found a deal on a GForce GF4A over the weekend and bought it.
the gearing is a bit off, but I figured I'd have to do a bit of reconfiguring anyway.
for the price I paid for it, I can replace all of the gears in it, custom bellhousing adapter, clutch, flywheel, etc, and still be ahead over buying a new Quaife or Taylor box!
