Master cylinder/ Brake Booster question?

[yellowGT]

I recently drop a rebuilt motor into my truck but I want to pull it out and organize the firewall a little by taking the a/c out and the brake stuff out too. I recently saw a post in which i cant find anymore where one of you guys had a master cylinder that hides under the dash. My question would be where to find those setups or if it could be built at home? I would of course have to get rid of my booster but would that have any affect on the braking? Any pics would be highly appreciated. Thanks.
