Brake Master Cylinder Replacement: F100 Stepside

We are back to working on my 1977 F100 stepside that I bought a few years back. This truck will be my new shop truck and any ideas you guys have for the truck, be sure to share in the comment section
The Brake master cylinder I'm using is one I picked up from ‪@DormanProducts‬

Hope you didn't get rid of those bench seats they looked like they only needed a little cleaning
