Without a map. The shortest one is probably the one to the drivers side front, from the T on the driver's side. There should be one going from the master straight(kinda) down to a T attached to the frame. - A crossover goes from that T to the passenger side, hugging the inside of the crossmember at the front of the engine, where there should be another T attached to the otherside of the frame. One from there down to right front and one goes to the rear.

If you have not taken the old ones off, study it and take pictures so you have something to work with.

I bought a pre-bent set from Inline Tubes and not one fit. Had to bend my own.

PS: I just saw you don't have the old ones. Are the T fittings still attached to the frame? If not, maybe the bracket is there to give you an idea. It will be a bracket with about a 1/2" hole. The T goes in there and is C clipped to the bracket.

Look for a few good photo albums of resto jobs others are doing. Usually the brake lines show up very nicely with the engine out.
