Help with the wiper arms

[HiluxSurf SSR-G]

Hi,
I removed the wiper arms to remove some debris that has accumulated in the cowling but forgot to separate/identify the LH and RH wipers. It was only when I was returning the wipers that I tried to identify which one was LH and RH and found out there was no mark to identify the RH from the LH. The only difference that I noticed was that one was about 1/2" longer than the other one. Also, the longer one has the number 5521 1B stamped near the u-hook of the arm. The longer one also has a slightly different bend angle near the u-hook. The shorter arm has the stamped number 5520 1B.

Would anyone be kind to check their wiper arms to see which one is RH and LH? Appreciate your help. Thank you.

On mine, 5521 is on driver side, 5520 is on passenger side.
