baddad457 I haven't come across a factory power brake set up yet. The space is tight enough that you willingly gave up power brakes? Hmmm, I better get a good close look at one to see if I want to wrestle with it or not.
There are a couple boosters from other cars that will work, I don't have one but a search should bring you up to speed. Like baddad was talking about, the factory setup is bulky, ugly, and right in the way. I'm using a Wilwood MC manual with 4 wheel disc brakes, can't tell you how the pedal feel is, as I haven't finished the install yet. Actually I haven't had a chance to work on the car in months.
The factory setup uses a different pedal hanger too, this hanger angles the booster and master cylinder up and towards the passenger side, filling the space between the firewall and shock tower, it also puts the brake lines between the master cylinder and the valve cover. It's an effin nightmare, that's why I converted mine to manual brakes. The pedal effort isn't that hard with a manual setup.
