Or extend the existing lines up to the new proportioning valve at the booster? I'm wondering because with my '66, I'd have to switch out the distribution block anyway, due to the single bale master cylinder for that year.

no, I would run an adjustable prop valve in the line exiting the dist. block going to the rear end - I would not use the combo valve.
