My wife and I currently have two shelf units in our house:

These are 25+ years old and I would like to make a 3rd shelf unit that
is similar to these. I can find shelves with no problem but I am
having a very hard time finding the upright rods anywhere. Here is a
closer pic of the rods:

They are 14 inches high and about 2 inches wide. I know I'm not going
to be able to find the exact uprights because these are so old (and it
doesn't matter because this unit will go in another room) but I can't
find anything anywhere like these. I've checked the hobby shops
around here (Michael's, Hobby Lobby, etc) and the hardware stores
around here and can't find anything. Are things like this even sold
anymore?

Thanks.
