9sp X0 shifter - spares or repair

Selling a red 9sp X0 shifter, in nice condition, however i broke the up shifter a while back. Managed to replace it, but I'm cack handed and must have not put it together again right or something, either way the down shift lever doesn't return properly. I've tried fixing it a few times and can't figure it out, so I'm selling it as spares or repair. Sold as seen.
