    I mentioned this in someone's banger thread, and didn't want to derail it by posting photos.
    I'm swapping for juice brakes and splurged on the BB battery box/ master cylinder rig.
    It's super well built, i have no complaints.
    I wish i could have found some photos of it in a car, beforehand though.
    I assumed it would mount to the top of the rail, but it's designed to hang below.
    It makes sense, with the floorboards and everything, but i didn't expect to see the whole thing from the side.
    Possibly, i can get aprons, or maybe it won't be such a big deal when the drivetrain is in.
    I have it wedged in for these pics, it's actually supposed to be mounted underneath.
    If you have one, post a photo of your car, so i can see how it looks.
    Thanks. 20230525_152509.jpg

    It won't be lower than the oil pan, or the bottom of the transmission.

    Have you contacted Boling Bros?

    No.
    I don't really have anything to complain about, but on a low car it might be something to consider. The m/c is lower still.
    It'll be awhile before the motor and gearbox is in, it wouldn't suck to know how it's going to look before i get that far.
     
  5. I am sure you will see a fair amount of it but on ANY Model A on a stock chassis you end up with a few items hanging in the breeze down there such as exhaust

    Thanks.
    It's a really well-built piece, i don't want to put anyone off.
    I suggest calling to see what m/c it includes. The guy i spoke to said there were supply issues, and they were going to switch to a different style. It sounded like that was already in the works.

    You might also want to choose the battery you intend to run. Once you know how tall it is you might be able to raise the box up. I moved my box to the passenger side but with a 1/2 inch clearance to the floor you can see how much shows below the frame. A bit of semi gloss black helps to disguise it. IMG_1246.JPG

    There are many small batteries available today that might help you show less battery box. I've never bought any from them but Speedway has quite a selection of batteries. There is also the trunk.

  9. I wonder on that M/C info as F-1 masters have a regular 3 bolt flange; while Jeep masters use the 2 sideways thru-bolts that fit the BB's box.

    Have you attached the M/C to see how low it hangs?

    Here’s my solution
    2 x 6 volt batteries in series to give me 12 volts, in my coupe, the floor has been replaced at some time, with a flat panel, so clearance is a bit tight, with an original seat. A bit of a mess at the moment, not finished yet

    You're right.
    I called before ordering, to ask what that m/c belonged to. One of us mixed that up, although i never gave a thought to how it mounts.

    The purpose of the Boling bros battery box/ brake cylinder is to convert to hydralic brakes. The battery box is used to hang the pedal assembly and the battery box takes the place of the old stock one. The master cylinder hangs down below the box.
    My concern is that the master cylinder is a single as opposed to a dual cylinder.

    The single circuit thing bothered me for a minute, but everything will be new.
    In high school, my daily was a beat up Triumph. It had a block in it with an internal shuttle. If either the front or rear circuit failed, the change in pressure would move the shuttle, and almost stop the fluid escaping.
    Not perfect, but at least you'd have some braking until you were off the road.
    That may be pretty common, but i've only ever seen it in Triumphs.
    Maybe i'll try to incorporate that in my system. I do remember that car having different threads and flares, though.

    That is a nice looking piece, and I wonder how much trouble it would be to mount two singles side by side on it, like my friend's IMCA stock car has.

    I put an optima under my seat as well. I'm still running 6V, so only needed one...

    It nice to buy & install , some times Not!
    With some thought , tools , fabrication skills M/c can be relocated pretty much any where ,,, It does not have tobe right @ brake pedal

    The stock Model A battery position is in the same spot as the Bohling Bros box.
     
  19. Forgot to say, that Stinger comes with it's own box. I added the hinge to support the battery.

    Speaking of smaller batteries/was employed by Harley Davidson for 18 years. Always had hot flathead ford v8 hot rods. One day a customer brought in his full dresser and wanted a new battery(old batt was 3 years old, functioned properly, but he was afraid of being stranded) He purchased a new battery and I “took” the used battery home hoping it would function I’m my 39 ford truck(flathead). The used battery spun the strong stroker flathead like a Chevy with the plugs pulled out(spun rapidly). Have used Harley dresser(some call them baggers) batteries in several hot rod Ford and always had good cranking ability. Flatheads Forever!!

    Exactly... uses the same location and the same battery size and hooks up to the stock brake pedal. A great retrofit for a fully fendered car.

    My 32 roadster has the battery mounted under the bottom seat cushion on the passenger side. I have a 2 inch fabricated metal seat riser with a fabricated battery box and we made the box deep enough so the top of the posts just cleared the wooden seat bottom. I did the same thing with my deuce sedan delivery, mounted the battery under the stock 32 passenger seat which hinged at the front and flipped forward.
