Early 70's brake conversion HOSES.

Those appear to be the cop brake setup with drilled & slotted rotors.
You still haven't mentioned exactly why the hoses don't fit your brackets.
Are you front mounting or rear mounting the calipers?
If you are rear mounting the calipers and the hoses are too short; then yes, the F/M/J hoses are longer and will work. '69 Camaro disc brake hoses are said to work too, although I have not personally used them. Source them locally or from RockAuto or Dr. Diff.
