Carb Fail: Butterfly Shaft P/N?

[HiImNewHere]

Apparently at some point in my carb disassembly, I bent the butterfly shaft for bank 3...upon reassembly I couldn't get the copper valve to fit and noticed the shaft was twisted. I messed around with sanding it down and correcting but all to no avail...the shaft will have to be replaced. I tried to decipher a part number from the terrible parts diagram but couldn't locate it. Does anyone know it's part number?
