S60R and BA Falcon XR6T bosch 'green' injectors are both p/n: 0 280 155 968.
So, in short, you could search for set of used XR6T injectors and find yourself with a spare.
The caveat here, of course, is that there's going to be a heap of XR6T injectors, variations, genuine and rubbish out there, so you'll need to tread carefully picking up a set and double check things before handing cash over.
1/ Check that they're green
2/ Check they're genuine bosch (or Ford boxed Bosch)
3/ Confirm part number is 0 280 155 968
