Making brake lines is not a bad task. You will have to obtain a double
flare tool. They are simple and straight forward to use. The fittings on
my '70 are all 3/8 x 24. I would suspect that they are the same on the
67.5. If you can find a pre-made length close to the original by all means
use it.
It will require a complete system bleed at this point. This is something
you should do once a year anyway. Brake fluid is 'hygroscopic' meaning it
absorbs moisture like a sponge. I suggest that you get a set of 'Speed
Bleeders'. You can order them over the 'net. I saw them at O'Rileys auto
supply the other day. They, too, are 3/8 x 24. They have a check valve
built into them to allow one person bleeding. The clutch fluid needs to be
changed as well.
