Interesting article. Thanks for the heads up.
I would not have thought that your run of the mill copper tubing from your local hardware store would be of concern.
My main reason for contemplating its use ...? Now that I'm writing this I can't think of any.
I planned on securing the tubing to the inner side of the frame rail. So for purely cosmetic reasons I suppose.
The copper (polished) would look nice up against the candy red paint. The black hoses that come with the kits will do to start.
We'll see what happens when I get all other parts fabricated and I'm ready for the hoses/tubing.
Just remembered. I might try to conceal the brake lines inside the frame rail. Especially at the front frame section where they may be more exposed.
That frame rail has an opening (presently covered) near the rear of its length where the line could reappear.
The concern with that is how to make the attaching point where the flex line meets the frame rail.
If I use the flex hose that comes with the kit, then I could run it all the way, through a grommet up the rail (inside) and out again just before attaching it to the master cylinder. However, that won't be so easy on the driver's side, with the steering box and frame rail in the way.
If I used copper tubing, it could be shaped to go around those obstacles.
Hmmmm ...decisions, decisions.
