Hi, i am looking for a brake booster with brackets on the outside or inside of the firewall. i have a 4 bolt master cylinder and disc brakes front and drum brakes rear. i want to keep the original wiper fluid tank and not have it take up so much space. What booster should i buy? the one i already have needs alot of pushing in the beginning and starts making a hissing sound then it becomes really easy that makes braking sketchy. PS. I have a 1969 dodge dart GT with a 360
