Also after one on these?
Or a shop that can make one in Melbourne?

Again custom part, USA, Hux Racing, RacerX (original one had some design faults and heard the new ones not as bad as you had to remove the intake manifold to adjust the bracket), there was a supplier in NZ however I believe they were only for 3sge (however listed for 3sgte but wasn’t).
If you are prepared to be awake at 1am, RacerX and other USA suppliers do a Black Friday sale with decent discounts on selected parts. Just be aware it’s US Dollars, plus shipping, plus insurance, plus GST.

Thanks for the heads up.

If you fit a lightweight aftermarket one, I would recommend you pay special attention to the fastenings. Maybe use Loctite or locking wires on the bolt heads, as well as periodic checks to make sure nothing is loose.
That OEM bracket is massive with many mounting bolts for a good reason.

I had one of these on a Mr2. I would not bother getting an other. Impossible to tighten in the engine bay. Ok with motor out. Unless you have a circuit car and your trying to save a 10th of second. Save your money.
