Find part numbers ala ETKA – Access possible? Alternatives?

Hello, I would like to check out part numbers for various screws for my Skoda Karoq Sportline 1.5 TSI 150 PS BJ. 2019. It’s about the classic screws of the wheel suspension to VA and HA – I build a KW suspension and replace the screws – Eben Federbeinklemmung, transverse handlebar, carrying joint, at the HA from the cross handlebar, at the top of the dome of the VA and HA, etc… But as a private person I still find the Tei somehow and at all I can say that on my own, or do I have to “stop” the dealer and this one if he does it at all? I would have to have insight into the catalogue and show the dealer which screws and nuts I would like to have… Would of course ala Erwin also pay for it, no topic – But I would like to do it myself. Thank you in advance and greetings
