Okay it looks like the TPS is attached the the accelerator pedal... unless I'm missing something? I'll attach some pics. You can't access the screws that hold the module to the pedal because its kind of glued over.
If I'm going to post it I'd probably prefer using the office works parcel stuff because there is one right next to my work. Is the Bendigo office works near you? Postage for the full pedal would be ~$13 I believe.
sfedek unfortunately I changed jobs recently and no longer work near you. I will be starting to pull bits and pieces over the next few weekends so if there is anything you want then let me know. I often travel down your way on the weekends so I might be able meet you somewhere.
