I used a ring and open (rachet) spanner and and had my finger behind it. You can just about do it, just takes a bit of patience. Once you get a few threads down, it gets slimmer - at this ponit you can no longer use a rachet ring spanner as it’s too tight and you must use a regular ring spanner
Hey Bruce! I hope you are well and thank you for your kind previous comment - means a lot, especially when the online world is full of hate! Please don’t quote me but I’m 99% sure it’s 13mm (or 1/2 inch if you are on them) It’s a nightmare to get too, but easy do able’ it’s also not too tight
Thank you, I want to get a long spanner to do the job, thanks for video, it is the most helpful as that bolt is what I've been trying to locate, I have watched many videos that essentially tell you nothing, you 3 minutes has given me all I needed, thanks again
