You can keep both with some fabrication. For the clutch, mine worked with a mid 70's bellhousing and clutch set-up with no mods. The brakes can be mounted on the fire wall. Just line it up with the pedal rod so they match and fabricate a bracket to push a clevis and pin equipped master cylinder (can't remember from what donor to get one from). There's conversion kits for almost anything that you may want to do to this era truck also,
Good luck,
Scott
