I found a place to buy brand new OEM JDM side markers for only $35 shipped.
I bought them from a place called PartSouq in the UAE.
I was skeptical at first, but they had great reviews, so I decided to buy them. Shipping only took 4 days too, which is unreal because two of those days were on the weekend and Easter was Sunday.
Here's a picture:

They also have them on their eBay shop, but they are usually out of stock and shipping isn't combined.
I hope this helped someone.
