Mmm 1 - 1 1/2"  with that power booster might be about right, I have found they tend to drop a little.. If its a VH44 try plumbing to all brakes. I take it you have adjusted your brakes up?
Dodgy stuff on the car hey.. Mate they ALL seem to have dodgy stuff.. Pfft!  Yet to come across a "perfect" one..
I'll chase that guy up about the valve covers..
cheers,..

I cant see real well how you have plumbed up the booster as I can see two lines disappearing. Should just be line from M/C to back of booster then the line out of the "nose" of the booster down to your junction  [for all brakes]

Now I want to know where did you get your valve covers!!

I think Old Irish Dave has long gone. There is a guy in QLD that sells the stuff that would normally make up that "kit" Its where I got my VH44 boosters from.  Ill see if I can find the link http://www.ebay.com.au/itm/BRAKE-BOOSTER-CHROME-8-INCH-DUAL-DIAPHRAM-MASTER-CYLINDER-BALL-MILLED-CHROME-/160957132529?pt=AU_Car_Parts_Accessories&hash=item2579caeef1   This should get you started to see what he has Im sure he has the brackets too ..$25 ?   Maybe check with us before you leap in IF you decide.

Here are a couple of pics of how i fitted my booster.

I’ve found some better pictures of the factory brake booster line routing but picture posting on my end has been down since the last software upgrade. For now I’m stuck with simply putting up links of pictures that are already on the site.

Guess you would be aware now the VH40 is for disc / drum application. You would have been better with a VH44 you could have plumbed it straight up. ..Bugger.
I just added a VH44 to the front [discs] on my little Triumph.
Im about to add a VH44 to my 35 pickup, drums all round.
My 56 Fairlane on concessional has the old Irish Dave power dual  circuit setup.  [see as Rick said]

I bought the booster about a year ago, can't remember if 40 or 44,

Not a very good picture. I'd like to see a better one if possible. I have a Midland booster I'm planning to install.

In the late 90's I put disk brakes on the front of my 55 bird, using a common kit. The kit came with an OEM style booster, which boosted the front disk. There were replacement wheel cylinders for the rear drums. Supposedly, the "self energizing" drums, with the proper size cylinders, a dual master, and the boost to the discs in front, would balance. They worked for many years, although the rears did lock early for my taste. I suspect you'll find the rears don't see enough pressure to work properly, and in the event of a failure, nothing works. I had a brake failure, single system, when the line on the rear axle fractured. I never forgot that. I also had a straight road, no cross traffic a manual, and a good handbrake.

In the days of the early GT Falcons only the front brakes were boosted as they had disc brake front and drum rear with a dual circuit master cylinder. The Aus Customlines boosted both front and rear. As stated the wheel cylinders do the brake pro portioning. On a single circuit system with the front boosted and the rear non boosted, I cannot see how the system can work safely. The remote booster acts as a vacuum assisted master cylinder.
I am on historic registration here in West Australia and run a pedal vac system. If I had been confronted about using the booster I would have simply just used the dual master cylinder. In my opinion single master cylinder systems are dangerous. I have had a brake line burst and thankfully had a good working handbrake and manual transmission. With an automatic at highway speed I doubt a handbrake would stop you safely.
I think you received information that "may?" function if you used a dual circuit master cylinder with different hydraulic requirements but certainly not for a single system with drum brakes. What they have done is completely muck up the brake balance.
You will undoubtedly run into the main detractor of drum brakes in an emergency braking situation. Brake fade - as the rears will not be working.
