Which bearings in my headset? (FSA Orbit C-40, 1 1/8" upper - 1 1/2" lower, integrated)

Hi all,

Need to replace the bearings in my headset on my winter commuter bike as despite cleaning them up they are making a horrible noise. Think the lower bearing has been replaced before as it has one of the old type of cage and ball bearings, some of which are missing!

Thankfully when I bought the bike I took a pic of the spec sheet so at least I know what headset it is!


Thanks for your help.
