1965 GTO Hardtop 389 tri-power (WS), close ratio M21, 3.90 posi rear (ZK)
I am an originality buff with a '65 GTO (389 tri-power, M21 close ratio 4spd, 3.90 posi) restoration project. My brakes are manual, but I'm torn about how to handle the old-school single fluid system (single chamber master cylinder). How do I try to maintain as much originality as possible, while having some level of redundancy (or do I just rely upon the cable parking brake with handled pulled in the event of an emergency fluid loss)? I'm sure I'm not the first to face this issue. Thoughts/suggestions would be appreciated.
