Best bet is probably a breaker.
I would think it's common to a few other cars as well, that use the same basic engine, Fiats, Alfas, Lancias, others(?).
i have tried loads of breakers but nobody will let me have the sump mines got a hole in it so desperate for one even with a stuck plug would do to get me out of trouble
Mine to has a hole in the sump I have fixed it using chemical metal, just make sure you clean the sump with brake cleaner to get rid of the oil then sand the area around the hole then put the chemical metal in and around the hole
job done
I bought mine with a bad repair so don't no what it looks like underneath so change is better for me, you can get it welded but where I can't find anyone to do it, you could make a living welding ally
