I used an aluminum master from a 83-94 s10

If I recall the lines are reversed: my original master cylinder front port went to the front brakes and this was opposite.

Some of the choices will be affected by caliper piston size, pedal ratio and how you like brakes to "feel". Bigger pistons need more fluid to move them so a bigger piston but that increases foot pressure to get the same line pressure.
15/16-1&1/8' seem to be common for most folks, or the equivalent metric piston sizes. Too small and there is move pedal travel to move the same volume.

I have roughly a 15/16" on my Wilwood Dynalite front/D154 rear caliper setup on the 79 Camaro/IA car. Started with a 1 &1/16 but the pedal effort the firewall was flexing some.

Strange has a couple of Mopar style both larger than 1" but you can cross reference different Mopars (minivans etc)in different sizes-what i did. bolt spacing slightly different than GM but a die grinder makes them work
