What brake hose for 74 dart with front 10" drums

I have a 74 Dart Swinger with manual drum brakes. There's 9" on the rear and appears to be stock and 10" on the front, possibly an "upgrade". My problem is the flex rubber brake lines are not correct. I need to know what it's supposed to look like from the main line to the slave cylinder (1.125" bore). They also used what appears to be a disc master cylinder which makes no sense to me.

Short of someone on here knowing the answer, I would recommend calling brakeequipmentwarehouse.com out of Minneapolis. I used to work a couple miles from this place and they supplied NAPA and other parts stores, as well as just about every repair shop in the area. They now have an online deal but I think I would just call them. These guys always had really good prices and LOTS of options...like maybe half a dozen quality levels for just about any part you wanted. Think of them like Rockauto but you can actually speak to a person.
