I know that these will be expensive to ship to Aus but I would imagine they are probably fairly hard to come by nowadays. I bought one for my V37 1966 Self Propelled but they fit a lot of other impulse starter models of the time, Corvette etc. as listed on the pack. This ebay seller still has 3 more available:

If anyone needs one I would be prepared to help.
