I bought the MBM brand front disc brake conversion kit for my 69. I am going from manual 4 wheel drums to manual discs on the front with the prop valve moundted UNDER the MC.

Some vendors say I need to purchase a brake hard line kit as the factory stuff won't work while others say I don't.

Any advice from someone who has done this same conversion would be greatly appreciated!

Nobody has used this kit?

I'll answer my own question after the fact in case anyone is searching for this answer later. I was able to use my existing brake lines. Had to do some bending and get an adapter or two but they worked.
