Hey 6BANGER,
R34 is different than R33 arms and silvias are a no go as well. Only R34 arms will fit, super cheap doesn't do wiper arms just the blades.
See www.wiperarms.com.au
At the moment we only have a passengers R34 in stock but if you want to get a drivers to please let me know and we will try to source one for you.
Hope this helps.
Regards,
