Bulbs Climate Control Panel and Screws ABS/Tracs SG

Hello together…. Let’s ask a question, maybe someone has an idea…. Meanwhile we have been able to successfully repair my ABS/Tracs SG. Thanks again to Terwi and Lucky CD! Unfortunately, the four screws are no longer ok, but the device is currently installed again and for almost 14 days and several kilometers the lamps no longer shine. However, we would replace the four screws with new ones, because the heads are completely unusable. However, these screws are no longer available to buy, at least at a Volvo dealer in DA and at a part supplier (everyone knows it) in HH. Does anyone have any idea where I can get these four screws or a suitable replacement? The three lamps/lamps for lighting the climate control unit cost a proud 6 thalers per piece. Is there probably only as an original replacement and not from Osram or/and Co…. Someone an idea how to bring the completely dark operating part back to lighting more cost-effectively?! VG Bird
