Hi drnick, i searched high and low and read an awful lot of posts on various auto forums, and I believe these two are probably good:
Princes Motor Repairs, 372 Lygon St Brunswick East ph: 93872192
Cox Auto Service Centre, 88 Buckhurst St, South Melbourne ph: 90710560
If you end up using either of them, please post again in this thread letting us know what your experience was like.
Best regards, Nicholas.
