7 1/4 2 piece brake line , how does it go on

^^ Every car is a little different. That longline basically oe from the dist block back it will do thru the sub frame thru a small hole then go along inside of rocker, you will either see clips there that hold it one, or holes for the clips to go in there it goes back to rear wheel housing and over from there to where the rubber rear end hose attaches Those clips can be bought from In line tube if missing.
