power brakes for 440 a body?

I have a 76 swinger with a 440 in it. The install was not really done very well. I have a good grip on everything that I need to do the install properly except for the power brakes. The valve cover has been modified to clear the booster but it looks like crap. I think that I could gain alot more room:? with a hemi brake booster but I am not sure if it will bolt to the fire wall. Does anyone know if a 8" brake booster with the hemi brackets will fit? Or am I doomed to remove the power brakes?http://www.forabodiesonly.com/mopar/images/smilies/icon_confused.gif
