    the firewall re-enforcement plate is different  for power brakes
     the booster mount moves the booster higher & then uses the double pivot linkage to hook to the pedal

    Thanks Chryco Psycho  :)

    I can see at I will need a diskbrake reinforcement plate.

    I have some holes in my firewall there almost match up with the booster. I think at the earlier owner has drillet them Mayne he has been a littel dizzy.

    If my car is born without booster. should i so have booster holes i the firewall or only have a small bolt "pattern" For the master cylinder.

    I think at i have the double pivot linkage "picture"

    Thanks Guys

    the holes for the booster will be in the firewall higher up hidden by the plate which you will need , the double pivot link is the part you have in the picture

    Manual non power brake re inforcement plate is different than power brake re inforcement plate.

    I just went thru the same thing with my OEM Bendix booster.
    For my application, I bought the power brake re inforcement plate.
    I bought the manual one and after, found out it wasn't the right one.

    For the original Hemi Bendix brake booster it's supposed to be a manual re inforcement plate not a power.
    My apology on any confusion.

    Quote from a seller on E bay that sells quite a few of the Hemi bendix boosters on e bay.


    Hello,
    Yes it fits the manual brake plate. All you need is the plate, Master and the C or B body booster one would already have. 

    Here's a power one.

    The manual one has additional holes and the center hole is kinda triangular.

    The B and/or C body ones have like a 45 degree slant on the top I believe.

    E bodies are square with a small notch on one edge. That, I know for sure.

    One more thing to make it even more confusing. There are 4 patterns of re inforecement plates that I know of.

    1. power square..4 holes only, short in size
    2. manual square...6 holes, triangular hole in middle
    3. manual square...6 holes, round hole in middle
    4, slanted top...B and/or C bodies.
