Holley Pump Discharge Needle?

I'm half-way into reassembling my 4160 for the first time, and i
realize i've lost the pump discharge needle and the ballweight. Where
do i go to replace it? The places i've checked online carry the
wearables/tunables, but not the needle. Am i going to have to buy a
used carb off ebay just for the needle?

Thanks,
Jeff
