disc front.my situation.best next step?

[dmartin1]

69 Shortbed. Factory power drums I think.
I want 5 lug disc front.
I made the mistake jumping the gun and bought all 4 new Moog ball joints for the 69 cross member and its all to bare metal ready for paint now.(control arm bushings were nice and tight I left them in and greased them)

Should I discard this and get a 73-87 front and then redo it? Or just buy the conversion drop spindles and everything else for a 71 and put it together?I could go to the junkyard and grab most(just for now, and use for core later for new ones.the truck just needs to be put back together I'm starting with basket case.)

What would you guys do? The budget fairly tight.
