The front mount onto inner part of swinging arm has horizontal slots allowing lateral movement to front of mudguard, although mine needed bolting hard over to one side of slots to centralise. Assuming side mounts to top of swinging arm are positioned correctly, bending them to move mudguard laterally is another option.
Remember mudguard clearance to underneath of tray is a consideration as well.
