Thoughts on Drum to Disc Conversions…

First of all, this thread has been really helpful so thank you all. I wish I had found it sooner.

I have a 69 Dart Swinger 340 that came with factory power drums and power steering (swapped to Borgeson/saginaw pump). Power booster is pretty much useless due to a prior owner's cam swap (hey, at least it sounds fun...). I bought an SSBC SBP front disc kit and had that installed. I was thinking about combining it with a hydratech hydro-boost set up, but before going down that rabbit hole, I wanted to try swapping to a manual master cylinder based on the input above. Any recommendations on what master cylinder to use?
