    Exclamation Power brake booster

    it appears my 89 lebaron needs a new brake booster.
    this car was originally TBI with 14" wheels and I have converted it to Turbo and plan on converting to 11" front brakes.

    I already have a new master cylinder for the 11" brakes, which brake booster should I use?
    parts catalog lists a single diaphram, dual diaphram and something about with or with out a site glass.

    is there really a big difference? would there be any significant size difference or fitment issues?

    doesn't really answer my question.
    brake swap will happen in the future, but I need a booster now.
    I would prefer a new/reman booster over a used one.

    Guess I will go with the dual diaphram unit.

    Any parts place worth their salt should be able to tell you which style came on the R/Ts.

    yes, a Spirit R/T. If you get a brake booster for an R/T you will be sure to get one which will work properly with the big brakes later on.

    R/T Spirit/Iroc.

    Why so special, because they came with 11 inch front and rear disc brakes, so the setup is matched. Remember to use the matching prop valve.
