Think i did that once, had to file the little notched things & beat the old ones out, then pressed the new ones in with a vice (broke the vice at the end of the job) and while i saw someone had welded washers on the ends of one driveshaft i took apart to keep the cups in, which would make later replacing easier i think that looks rangi, as does welding the cups. Maybe using a cold chisel to stake them in a few places could work but as i never tried that on such a modern car the cups might move & the balance would be wrong.
