[Closed] Nukeproof/superstar pedal bushing replacement

My nukeproof pedals have quite a bit of play in them. I've stripped them down and the culprit seems to be the pedal bushing. Has anyone removed and replaced these? How did you do it? What side do they come out? Is there an obvious lip to avoid? It's all pretty dark in there.

A web trawl has revealed very little and I haven't heard back from nukeproof's technical support yet, so any advice would be much appreciated.

From the pictures on their site, it looks like very similar pedals are also sold by superstar.

Thanks!
