Need advice on Brake line parts and configuration

Sorry it is going that way. Damn Metric stuff.

In-line tubes has the orginal hold off and is what I used. It works fine but I certainly thought having some adjustability would be better.

lol no worries Gerald. it's all a learning experience And I don't mind sharing so others don't have to go through it :) I would have thought the valve fabricator would have standardized the fittings based on application.u
