Dittos here. My brake line was too long fore/aft and too short up/down. I zig-zag'd it 3-4 times in the tunnel to take up the extra length. You can kind of see the start of the zig-zag here:This would probably be my approach as well.
I went with this. And said **** trying to screw the lines in and used zip ties instead.Common issue. It really comes down to make it work. It won't always land exactly where the videos show. You can sometimes make some gradual bends in the tunnel without the tube bender. I think I made mine swap sides several times in the tunnel to take up some of the excess length.
I hope you clean off the paint or powder coating once you get that ground properly secured.
I would jack up that side of the chassis to make sure much fluid doesn't flow out.
