Nathan, Not sure I'm understanding which piece you are needing. Is this the ball stud on the end of the left side steering arm (see pic below with red box around part description) that the drag link from the steering box arm connects to?
If that is the correct part, the 1962 Chevy Master Parts book lists 2 different part numbers that can apply to your 1946 2 Ton. The key is the casting number on your axle to determine which arm is needed. I can't tell what the differences between the 2 are???

The ball studs do not seem to be listed as separate pieces, nor could I find anything reproduced being offered on the web. Perhaps another Big Bolt owner with a 1941-46 2 Ton can help you out with more info???
I did come across an NOS steering arm for a
1946 COE but that won't fit a non-COE 2 Ton.
