More brake questions..

For '75 Duster.

I see in my service book that there is a bracket at the rear of the car that allows the transition between a rubber hose and solid brake line. Is that available to buy or do I need to source it used and does it have a name ?

Is there a better exploded view of the front disc brake set up ? I am looking at the pile of parts I have and I don't have an assembled one to look at for reference and I cannot figure out how the caliper mounts and with what hardware. Sorry for the run on sentence.

Thanks
