I have the 67 manual MC with the same 1" bore size as my 65 manual brakes have. Raybestos MC36221 .
I will call Brewers on Monday and discuss with them if they think I will need to replace my rod with the one they sell. I have one for a 65/66 power brake setup on the shelf from MC change i did in 2014. That I reused the old one from my original on.
One big "gotcha" that comes up regulaly....
..... Make CERTAIN that you take steps to make this so. Mechanical measurements etc.
A popular way is to (carefully as the port(s) can spurt and geysher) take a helper to apply the brakes and release a few times and look for the obvious backflow back up into the master as you look down into it
Thank you @67Dart273 . I will make sure of this as soon as I get to this point. Will be starting on the work next weekend. When I get to this part of the install i will make sure of this.
