The drum brake wheel hub won't work with the disk unless you get the surface machined to allow them to mate together. I think 1980 was the last year for 6 bolt locking hubs so you could get the wheel hub from one of those and it should work with your spindle.
I just took everything but the spindle off a 1980 front end and put it on a later model widetrack and it all bolted right up. Both of mine were already disc though.
