Posting for help to anyone googling:
I measured the length of my 1980 cb650 brake line hose, and it was 43" , or 109cm.
I might buy from Spiegler, and the order would look like this:
Caliper End - fitting type 002
Top end - type 530
Grommet at 54”, 2cm by 2cm
Price pending (they make me request an email
I might buy from Apex
Caliper End - type #3
Top end - type 9
$50
Good luck everyone, and good luck me.
