I suspect a 105 group would fit just fine provided you got the correct threading for the bottom bracket bearings.

As for updating to a new 105 groupset . the points of concern i would say would be the Front Derailleur Clamp Size/Pull Direction. and the wheels/Cassette. if yours has the Campagnolo hubs still you will need to get new hubs as the campagnolo hubs will only take the 8 speed campy cassette (IIRC) .
The Rear Deraileur, Shifters, Bottom Bracket and Brakes shouldnt be a problem. and keep in mind the Headset is JIS standard not ISO so if you were planning on replacing keep that in mind.
Hello and thank your for the replies, I didn't expect such quick replies!
The dead parts are the triple Campagnolo Mirage crankset and the 8 speed Miche cassette (missing teeth). I wanted to replace these parts by new ones instead of good condition used ones in order not to have any bad surprises. It's also hard for me to tell if used parts are still in good condition, especially when the online pictures are not so good…
Unfortunately, new 8 speeds Campagnolo cassettes and triple Campagnolo cranksets don't seem to exist anymore. I was able to change the hub for a Shimano hub (I just unscrewed the old one and screwed back in a used 8 speeds Shimano hub) and add a new 8 speeds Shimano cassette but of course the indexing of this new cassette does not match the current Campagnolo 8 speed Mirage rear derailleur! So that means I need to find a new set of rear derailleur + shifters + crankset + front derailleur + bottom bracket…
So then I figured, why not just buy a whole new groupset (plus, idk why these replicas had all sorts of components from different Campagnolo groupsets (Avanti, Mirage, Veloce), my OCD doesn't like that…). So it looks like the current bottom bracket threading would be compatible with newer groupsets since it's a 1,370" x 24 which appears to be the modern standard if I'm not mistaken? But it also seems like all of the new road groupsets have 10, 11 or 12 speeds and I get the feeling these big cassettes won't fit this old Peugeot frame since my rear wheel is already almost touching the left side of the frame (as if this frame wasn't made for 8 speeds but rather 7 speeds?).
So then I figured, why not just sell this bike for parts and get a new bike? I fear that I will always have troubles with this bike because it's so old…
What are your thoughts? What would you do with it?
Enjoy your home stay
