Which booster do I need to find?

I want to clean my firewall and want to run a booster under my dash, which one do I need to find? Point me in the right direction would be great thanks.

lots of people swear by a geo metro booster.
i'm goin manual... no booster

geo would go under the dash? I typed that wrong and dont really care for the booster and would run manual brakes but want it under my dash

so what do you want? a mount to go under the dash? scrpnmzda just got a kugel 90*booster mount.
here's a link to his build thread and a pic of the unit

there should be two additional holes in the mount to put bolts for just the master cyl. if you omit the booster
