The early setup (my car is a '94) has hard lines running across the axle a bit like the older classic/discovery, which then jump up to the body/chassis from a bracket off the middle of the axle.
So i have Flexi from caliper to axle, hardline across the axle to a bracket, flexi from bracket to body/chassis, hardline to the front.
Except my axle is the later type and doesnt have the bracket. Someones bodged it previously by hacking the bracket off the old axle and clamping it to the newer axle with a jubilee clip. The later axle also doesnt have any provisions to secure the hardlines to the casing, so they're attached with cable ties. Its all a bit crap and thus I'd like to try and convert it over to the later style as per your pics.
The bit you've pictured i can understand, i need a new flexi and possibly i need to add a tab on the chassis to hold said flexi.
The bit i was struggling with, is what happens after that. Your car will have a short hardline that goes up to the top of the chassis near the spring mounts, then a flexi going somewhere, then eventually the hardlines to the front.
I'd like to run the hard line from the front, directly to the flexi in your photo.
