Bleeding Brakes - 9" Drums

Fwiw - I took delivery of the car 1 week ago. The guy I bought it from acquired it as part of a trade, but otherwise knew little about the car and had little overall interest in it. Good deal for me, rust free straight body and it runs. So the last week I've been in discovery mode.

Back to the brakes, the MC is not original to the car. From this thread and others I've read it's from a 67 or later. I haven't seen the splitter block y'all are talking about, but I haven't looked for it yet either.

To rumble fishes question - the brakes were nice and firm before the overhaul. Although I'm not accustomed to manual brakes, the pedal pressure felt linear to stopping ability.

I've bled a lot of hydraulic systems, but haven't had one kick my *** like this.
