Did you change your Master Cylinder pushrod changing fron single to dual??

The rod sets the position of the pedal.

As long as it is not keeping the master from fully returning to its resting position. And there is enough travel to fully apply the brakes it's fine.

Thanks, I picked one up, and will use it if I want the pedal in a different position after install today.

On my 66’ when I converted I used the factory pushrod (non adjustable) I had to pop apart a sheet metal clip that kept the push rod into the master piston. Sorry I don’t have photos for you. That was about 4 years ago.

Mine has the non adjustable as well.

I switched from a single to dual reservoir without changing the pushrod and with no issues. I used an A-body cast iron MC; you may need more length if you use an aluminum two bolt MC and an adapter.

Thanks this is the assumption I was making after looking at them as well.

I switched to a two pot and used the same rod for 6 years, worked great, perfect for my 66 Plymouth Valiant, now I have switched to a disk front brake with adapter, cut two brake rods to add another inch of travel for the 4 to two master cylinder adapter.

I am switching to disc but using the 67 MC. Won't be using an adapter on the manual brakes. The MC I used was the 1" piston.
