Do a little cruising of our past threads and you will find several of our Aussie mates that can guide you on your own home turf.  Our friend "Talkwrench" - Rob MacDonald - in Perth has been through the whole set-up you are asking about and by now- knows the drill for sure. He may know a good way to get the parts found and shipped - dunno for sure.

Your approach is common sence and easy. I have done the same thing on my Mainline Ute. I generally deal with Dennis Carpenter or Macs auto and I bought a reconditioned dizzy from one of them. I paid the core price and frieght but I generally get a few other parts as well. (the core price is cheaper than frieght).

I got it running on points and drove it for a while and converted to the flamethrower II as I like the safety cut off which stops it burning out. I bought the flamethrower II off ebay as pertronix does not seem to have a OS option for frieght. I run a bosch GT40 transitorised coil but would like a better one later. you may find one through that company you buy the dizzy from.

You will have to check prices as these have changed and the exchange rate always has a bearing.

Cheers

I will add that the referbed dizzy I got was the later three sided body type.

I have a (very) well worn y block unit you can have. The spring posts are almost worn through etc, etc, so if you are into some fabrication and willing to chance it, your welcome to it.

Cheers

(1) The Ford "Load-O-Matic" distributors depended on VENTURI vacuum as a signal proportional to engine speed. In effect - how much air is bing sucked down the intake manifold? This signal came from a carefully placed orfice in the caburetor venturi - vacuum was induced by air flow over the open orfice. The carb either has this port or it doesn't - Ted knows how to add it to some of the carbs that will accept the modification. Ford used this system on the Y's up to 1957 - with no centrifugal advance.

(2) MANIFOLD vacuum - simply the level of vacuum existing in the plenum of the intake manifold tract under the carburetor. Suction provided by the engine working as an air pump with the throttle at various opening levels. Can be a good source of engine information and tuning aid if you know the "signal" the gauge is giving you. Can be used as a source of vacuum signal to a distributor if the arrangement is designed and tuned for it.

(3) PORTED vacuum - In simple terms this a a source of manifold vacuum (2) that is regulated by the primary throttle plate of the carburetor. At idle the port is at atmospheric pressure - no vacuum. As the throttle opens, the port is gradually exposed to full manifold vacuum. Ford used this vacuum signal for the vacuum advance system on vehicles 1957 and later - to sum with the centrifugal advance.

That good to know. I was going update the coil, so I might give that company a go.
