I saw these on an aussie youtube channel and looked them up. They are for the 70 series but the site says that with a mod to the bracket it can work in 80s, 100s etc.
Just ordered a set for my HDJ81, so wondering if anyone has done the mod already to use them on an 80.
Price is in AU$, so with shipping to US, they came in just over $200. They confirmed on Christmas Day that they ship to US.
