Where to find work equip valve stems (90 degree metal)

I have been searching everywhere for these things, NOBODY seems to have a clue where to get them. One of them is missing and the other ones the rubber is cracking since these wheels are older. I was trying to get them today to mount my tires. Anyone know where to get them? Thanks.

The VS series valvestems look like they would work. Probably the same part.

And where to get them? Or anything locally that I can get that will work?
