Welcome Rowland
we are hoping to get a fair few Australian members as we know there are a good many 75's out there. Please let us know of ways we might help you and your countrymen (apart from losing the Ashes!)
I will dig out the details of an Aussie garage that contacted me in case it helps. They work mainly on Jags etc and have begun offering 75 work as well.
Pull up a chair and make yourself at home
