64 single to dual master swap

I have done it to my dart,
But I'll be darn if I can remember the sizes and lengths. All I can remember is I the hooked the back port to the front brakes. By running it into the distribution block. Then removed the rear line from the block, plugged the hole, and ran a new line to the front port on the master. You can join the new section with a union. Works great. And I feel a little safer having the duel cylinder. Do a search on hear and you will find some great right ups on it.
