You're serious man Goran :)

I'll find part numbers if you need although ETKA is self explanatory. I have purchased them in batches, so it'll be a bit difficult.

The only two seriously expensive parts are undertrays themselves, but they can be sourced from zee German eBay if you don't mind used stuff. Key words are Motorschutz or Unterfahrschutz.

The whole kit can be ordered all together from one salvaged car.

I will have a go on VagCat, shouldn't be a problem.
I dont mind used parts at all, no one is going to see it under there anyway. Thanks for those key German words!
I'm hoping I can get away with just the gearbox tray and mounting brackets, I am happy to keep my main under tray as it is.

Thanks!

That's a good plan Goran. You can leave existing engine undertray. You will have to change the rear cross bar of engine undertray because it now holds both rear of engine undertray and front of gearbox undertray.

When talking to zee Germans just ask for gearbox undertray, front crossbar for gearbox under tray and middle crossbar for gearbox undertray with all the bolts.
