New Brake Line Questions

[SierraM37]

SO I've got Ray's Disc Brakes and the Chevy MC installed and now it's time to run the brake lines. At Napa, the Armored line (5/16 or 1/4) come in lengths of 10, 20, 30, 40 51 and 60. Coupla questions.
Does anyone know the Qty. of each length to make the fixed lengths work?
Is it better to buy a spool (where) and cut/flare myself?
What did you use for the flex lines to both front and rear?
Does it matter if use 5/16th or 1/4?
Lastly, what about the brake light switch. Does anyone have a model # they used?

Thanks in advance guys. Hoping to have on the road this spring early summer.

You can use either type of metal lines you prefer to work with, NAPA also offers bulk line and fittings for custom making your own.

We have new flex hoses for front and rear axle to frame installation and for the front steering knuckles.

1/4" is what you need.

NAPA Echlin #113 stop light switch works well, wires attach with screws, we use these exclusively.
