You can get the banjo adapter in different angles and then run straight -3 fitting braided lines. Lay it out so everywhere it uses a braided line can use the same length and then carry one as a spare. My rear is set up like this except for the long braided line that’s running down my upper link to the axle. You can also get -3 caps/plugs to block off a line if you have an issue. If you’ve got a race shop local to you they may be able to make the -3 lines in whatever length you need. Or check out SRI Performance. They’ll make them however you want.
I've seen angled banjos, but only angled in line with the bolt, not perpendicular to it like the stock JK lines. It might work anyways though, I'll have to just mock it up and see. Any reason not to use right angle AN lines, other than them being less generic and less easily replaced?
Overall I'm leaning towards the upside down caliper idea because its 8 less fittings and maybe $100 less to go with the type of lines I showed above vs getting all the banjos and 3/8-24 adapters
I'm planning on using the same type of line at each caliper, then a longer line running down the upper control arms, same for front and rear. My initial idea was to run a short AN line at each control arm joint then a hard line down the link bar, that way every braided line is the same, but its also a lot of extra connection points and complexity just to have a single spare line vs two.
