i've never seen a 6 bolt BigUn, got a pic? As far as I'm aware, the wide PCD discs are 5 bolt, and the 6 bolt are the current smaller PCD which every hub uses. never seen a wide PCD 6 bolt disc.Hub is too narrow to be mk1
An mk2 were 6 bolt disc
Yours is the mk2 but they did do two different stickers for them as far as I knowI think you are correct just been looking I think I ve got confused looking at the shape of the hub I don't think 6 bolt would be possible
All the mk2 hubs I ve seen have the oval sticker like this
Mine has the old style HOPE sticker though
