Ok, I hope that I can describe this. On my 1970 c20 4x4 I'm doing a disk brake conversion. I got a set of ss braided flex lines for the front and rear (two for the front one in the rear) and all them bolt right up except for the drivers side. When it meets at the frame it needs a bolt (banjo?) to go threw the line from the inside of the frame to the outside where the flex hose would conect. Does anyone know the name of the bolt that goes thru both the brake line and the frame which connects to the flex hose?
