Looking for an MC Rebuild kit 1 inch bore.
I am looking for a master cylinder rebuild kit for a 71 CS with Power Drum Brakes (no disk).
The manual indicates that I have a delco morane MC with a 1 inch bore.
The MC on my car is factory original.
Most of the stores / web that sell replacement kits do not post the bore size.
A friend of mine doing the rebuild just bought a kit and got the 1- 1/8 bore, which we found out later is only for the cars with Front disk/Rear drum.
Suggestions welcome.

Thanks Retro,
I did find the #MK497 on the Raybestos web site, but could not find the bore size on the specification. Interesting the Rock Auto has the bore size clearly listed.
Thanks.

Need Secondary Piston
I bought a Master Cylinder rebuild kit from Rock auto with a 1” bore for my 71 CS power drum setup.
The kit had springs, gaskets and one Primary piston.
The kit does not include a Secondary piston.
My existing Secondary piston (aluminum) is all pitted. See attached pictures.
The question is, where do I get a Secondary piston with a 1” bore for my 71 CS?
Rock Auto does not carry them.
Below is a picture of my Secondary Piston. Notice the pitting.

I did end up buying a full MC and then removed the parts and put them in my original MC.
The new parts were identical.
Now I just need to paint and install and see whathappens.
Moral of the story, If you want to rebuild your old MC, just by a new one and swap the parts.
