Accelerator pedal

[Wat22]

Hello, I bought a Hyundai Tuscan Xenith in October 2008 plate, 3 months later there was a problem with the accelerator pedal and there is no power to accelerate when you need it. It will get up to speed eventually. I replace with a different model pedal but need the exact one. I can’t find it anywhere in the world. Checked Breakers yards and so on. I know it’s a long shot but was wondering if anyone knows of an Xenith model that is being broken for parts or where I could possibly find one.
Many thanks
