Front end rebuild kit question

[brandster]

My 67 has been converted to 5 lug front disk brakes at some point in its life. Im assuming someone probably used parts from a 72. From what I can tell, truck still sits at stock height and suspension is still stock.
My question is, the front end rebuild kits I have seen, the kit for the 67 and the 72 are different, so Im not exactly sure which kit I need. What parts of the rebuild kit (ball joints, tie rods...etc) would have changed when switching to 5 lug disk brakes? Thanks.
