Kurt, It's been a wile since I've installed a stock gearbox in a car, but my recollection is the fork should be pretty much centered in the opening. I would inspect for wear on the release bearing through the opposite fork opening. Also are you sure the fork is not bent? I'm not sure that disc wear would put you that far off center. I would also check your freeplay adjustment since you have the adjustable pushrods at the MC.
