A bit late to the party, but those are not DarkSoul V2 meaty bones. They're some sort of CVD. The outdrives are a dead giveaway. There's no groove for the drive pin to slide back and forth. The broken head portion was cut to pivot within the drive cup.
If you're still looking for something to replace these bits, Fast Lane Machining (FLML) is still building drive shafts and cups for our models.
