Looking for a new complete set of brake line tubing. Anyone know a good place to buy the kit. My 84's are rusted and brittle. Already purchased new rotors, calipers, hoses, and all new rear drums and shoes.

You can check these guys.

This is how I went.

If you make your own you will have to re-use your fittings or buy new. You will also need a "double flaring tool"
I was lucky as a very good friend owns a shop and let me borrow his.
Mine is by no means a "Concours Restoration" just a fun driver on pretty days.

I used a complete set manufactured by InLineTube for my '70...They fit perfectly with no modifications required. All the bends and fittings were at their proper locations and only very slight tweaking of one or two of the bends was necessary. I'm happy with the product and would surely purchase from them again.
