Mine are all rusty as well. Gonna change my brakes this weekend so need to get some new ones. I will buy a set with different sizes if i cant find out here. Will let you know the correct size then.
I got my hands on some bleed screws for the FL now. There are different front and rear screws. Both are 10x1mm, but different angle(?) or something. They just had the front ones. Will get the rear ones tomorrow.
Front ones are 34,3mm and rear ones 34,0mm. Will take some measurements over the weekend.
It is possible i have got the wrong ones. I just gave my reg plate nr to a big car parts store/chain here in Norway and this was what they/datasystem recommended.
