Anyone have any of these spare?

I have an I – spec B saint shifter and an Ispec B XT brakeset and a Saint I-spec B brake set and not one of these I-spec B components includes the barrel type hardware.
Shimano are backordered until June for parts Y6UV98090 .. so I’m on the hunt for someoen who’d mounted an ispec B to an older i-spec lever and might have spares.
I’m referring to the hardware in the (Assy procedure “in the case of B” box

Thanks in advance
