Just had another reply and he thinks i want to fit it to a different type of block, trying to explain i want it to go onto existing cooler.
I will get one then Lloyd as i can get different lengths of screws from my pals work.
If it doesn't fit properly and your gonna buy it from me then i haven't got anything to lose apart from your gtx 580 looking the dogs and mine looking shite.
I will just see what he says now as hes emailing me at the moment.
