Is that power brake unit bolted directly to the firewall??? How did you get that in there??? The factory units have a set of brackets that raise the whole thing up and foward

Looks like you have a big block (like maybe a 440?) in there. PB’s was not an option from the factory on M Code Cuda’s and Darts due valve cover clearance was one reason. Go with manual brake master cylinder- problem solved.
 
its a 383 either ill use a remote resavoir or an offset block like the hemi cars did to move it over and ditch the booster
 
Go Manual.

Use a 15/16" bore manual master cylinder for your Disc/Drum setup.

1" and 1 1/16" master cylinder bores push hard with little foot travel.


Here is a 15/16" Manual Disc/Drum master cylinder from rockauto:

.9375 = 15/16"

Application is 1973 Dodge Dart 340 manual Disc/Drum Brakes, 15/16" bore.

I have built a lot of street rod and race cars over the years with the clean firewall look currently building my 48 Plymouth Gasser using Wilwood reverse swing brake and clutch masters the picture just for reference there are also 90 degree right angle brake booster sets ups as well however I suspect you don't have the realestate to use either one but to be honest I heaven't explored the underside of the dash yet on our Dart, what I can tell you with 100% certainty is that it is NOT an easy job a lot of fabrication is involved and consideration needs to be taken for things like brake bleeding, I had a really slick looking 57 Chevy come into to my shop a friend recently purchased he upgraded to 4 piston front calipers and 6 piston rears how do we bleed the master and refill it answer remove the instrument cluster not a very well thought out job. My two cents worth as other have mentioned either go with all the factory brackets master et or possibly one of those mini street rod boosters again more fab work.
