My ones are from a R33 GT-R i believe, but there the same as a series 1-2 stagea in appearance. If your looking for nismo or dolphin side indicator replacements you can try www.rhdjapan.com - www.nengun.com - www.importmonster.com. All those websites have them in stock i personally recommend import monster and in the search terms use "wgnc34 led" you should be able to find the dolphin indicators with an ETA of around 4 weeks probably the same as the other sites.
Mine are not for sale anymore ended up installing them on my car and smoking them with some night shade they came up fantastic!
Best regards Chris.
