OK, problem is solved.
For future reference in case anyone else runs into this issue, it turns out there are differences between `67-`68 12 bolt brake hose brackets and the `69-`72 style. The `69 style rear flex hose has the t-fitting built onto it, the `67-`68 takes a separate line and t-fitting. I have the `69 style bracket which doesn't work with the `67-`68 line and t-fitting. A new `69 style hose will be here in the morning which
should solve the problem.
Learn something new every day.
