Gday there tikEK2,
I can tell you of a few places in the Eastern suburbs who could probably do the alignment job. Total Tyre Service (9569 8666) at 2 Park Rd, Oakleigh should have no dramas doing the job for you, I used to have satisfactory wheel alignments done there for my old Valiants and Valiants were notorious for chewing through front ends and tyres. If you're willing to head further slightly east, Tyrepower Blackburn is also good. They're at 176 Whitehorse Rd, Blackburn (9878 4511), ask for the manager Michael Cruikshank if you go there.
Personally, throughout the years I've had the majority of such jobs done at City & Rural Tyres (9553 3003) at 200 Chesterville Rd, Moorabin. Bill Prountzos runs this business which is a small one and thus offers personalized, very friendly service. I've found Bill a tops bloke to deal with and his work/products competitively priced.
Hope I've been of some help to you fella.
Cheers ...... Pete
