Picking a Master Cylinder

Well I decided I am going to go ahead and go with a under the floor master cylinder and brake booster. Only thing I need to know now is what size/kind to get. I see that you can pick between a 1" or 1 1/8" bore and not sure what that is or nothing. I just need to know what kind will fit the lines from my 79 Z 28 front end with OEM disk brakes or calipers and the rear end I am not sure yet but I am probably getting the plain explorer disks from Currie.
If you need more detail on anything to answer my question then please let me know.
Thanks for any help.

Ok I see, thanks man. Well yeah for the front I will have the OEM calipers from a 79 Z-28 and I have no clue what size bore they used on those cars and then I will have the rear ones from Currie which will be Explorer disks so I will have disks all the way around. I will call them and see what they think. It's more confusing than what I thought. I wish I could just find some kit that came with everything like booster, master cylinder, all the valves I need, etc.

I'll call them because I looked on their site and don't see nothing for 79's for brakes or anything. I appreciate it again, your a big help! What would I do without you guy's?!!! Heh
