I can verify that each year 1970, 1971, 1972 are all different when it comes to brake lines/hoses-especially on the rear end.

I swapped everything from my 1972 parts Blazer over to my 1970, because I want front disc brakes, and I had already purchased a 1972 pre-bent line kit.

Those rear line brackets are 1972 only, presumably only for leaf spring trucks/Blazers.
