I have a M/C for manual brakes and it won't fit into the hole in the power booster. It's too large.

Now that I think back to the two times I drove the car on the street and moving it around in the driveway, I do remember the brakes being very touchy.
For example: if was letting the car roll back into a parking space at 3-5mph. I would have to be very careful on the brakes, because if I applied just a bit too much pedal, the brakes would lock right up! I’ve locked the brakes enough to screech the tires a bit just maneuvering the car around at slow speeds in the driveway.
I just figured that’s how old brakes were, and I just had to get used to it, but now I’m wondering if someone at some point put incorrect wheel cylinders on this car.Comment

Remember that squarebirds don't have self adjusters so if they're not hand adjusted correctly they will grab.John Pizzi - Squarebirds Administrator

I did it on my '59 and it's pretty simple. I got my kits from Advance Auto parts. They're about $10-12 a wheel.John Pizzi - Squarebirds Administrator

The original M/C (or PB bracket) sandwiched three important metals together with four studs and cage nuts; the Brake Pedal Support Bracket, Firewall, and Master Cylinder (or Booster Bracket).
I heard about 'firewall flex' which didn't make sense to me because these four studs & nuts hold everything together real well. If only two bolts are used, I'm SURE the brake support bracket will flex at the firewall. I am too used to dealing strictly with power brakes and four fasteners at the firewall.
If your money is tight, you do not need self adjusters and rebuild kits are cheap. All OEM parts are simple and easy to rebuild IF your bleeder screws work.
For over fifty years, your car worked just fine using OEM parts. These are all the parts used in your M/C:
