Front disc brake hose fitting sizes?

Assuming all the parts (especially the caliper bracket for the hose) is all '72, just order it for that year. That bracket changed early on from a multipoint fitting to a round fitting with a flat spot to lock it into the bracket. '68 was still the early style and by 1970 they started the newer style. Not sure about '69. Not a big deal as the clip will hold either hose, but, why not just get the correct one to begin with.
