What’s involved in converting my 1965 Pontiac Tempest V8 non-power-brake system to a non-power brake dual master cylinder? Is it as simple as getting a 1967 dual master cylinder, bolting it in and then re- plumbing the lines? Can I get prebent lines for a 1967 drum system and use those? I’ m not ready to convert to disc yet; my old single-cylinder master cylinder (original) began leaking, so I thought I’d convert to the dual-cylinder for safety’s sake. (Sorry, I originally posted this to the general Pontiac site)
