Brake hose

If I'm understanding you correctly, I would stay with a 75 year hose set-up if that's what your using for your set-up on the 72. As long as you stick to a-body lines or (depending) on which hose/s you require, ask for say 73-76 duster. With calipers in the rear you "may" have to remove them and ask for a match if your not sure what they came from.

I'm sure others will add some info here. They may have better point or ideas then I. :salut:
