68 Barracuda front to rear brake line route

I finished all hard brake lines yesterday, more creative bending on the shortened 8 3/4. Ive got the 2 flex hoses on the front discs left and that's it. Now let's talk about the damn clipping arrangement of the flex end fittings. They're common, my Land Cruiser has same and I struggle with these damn things every time! Literally could not get the clip in on the rear flex.Am I missing something here!?
