1965 Valiant brake woes

I stated in the first post why I started another thread.
To get more eyes on it. To get advice on not making the best of a bad situation, which is what the other post was about, but on which direction to go now.

- Remove the power brake stuff and proportioning valve and try to get the stock drums working? If so, what to do about a pushrod, distribution block, etc.
- Throw in the towel and ditch it all forward of the firewall and go for discs?
