What shock absorbers?

Seat Leon 1.8 TSI FR, Bj2013. I would like to change all shock absorbers with dome bearing. The part number for the rear axle can be easily seen in the photo. This is a bit difficult for the rear axle, but I could decipher it by comparing it in the ETKA.https://nemigaparts.com/en/cat_spares/etka/seat/le/754/411000/ rear axle: 5Q0512011HHH Front axle: 5Q0413031FH If I now enter the divider with e.g. autodoc, then there are 4 manufacturers left and for Sachs this damper is then the Right: https://www.autodoc.de/sachs/14922297 But I don’t want Sachs dampers but Bilstein and below that I can’t find them with the part number. I have to trust the filter from Autodoc. Two dampers from Bilstein are recommended to me: https://www.autodoc.de/bilstein/9129438https://www.autodoc.de/bilstein/13653383 The first one is Multi-Link axle and the second rigid axle. Which one suits my car when you look at the Sachs above with the original part number? Be I don’t understand anything anymore. Actually I ask that because I would like to buy such a mega set of dampers, dome bearings and dust protection on ebay. According to autodoc the dampers do not fit under the link. According to the ebay list already. https://www.ebay.de/itm/403924971805 On the front axle I measured the outer diameter of the damper and that is 55. What do you think? Should I buy this set or not?
