Gene -

Something's fishy, there. To be honest, there's no Advanced Auto Parts stores close by, but I know they stock the copper-nickel stuff in the Youngstown, OH stores. It can also be ordered online; here's a link to their page for the 3/16" stuff:http://shop.advanceautoparts.com/buy/products/113516-nickel-copper-alloy-brake-line-coil-3-16-x-25-by-nicopp-part-cnc-325-hardware-fasteners.html

Plug your own zip code into the "Check Availability" box on that page; the truth is out there.

I got the stuff for dealership stock from stores in my area that were affiliated with the Federated Auto Parts and Advantage Auto Stores chains; dunno if you have any of those in your area.

FWIW, here are the supplier part numbers for the four sizes that I'm aware of:

CNC-325 = 3/16" x 25'
CNC-425 = 1/4" x 25'
CNC-525 = 5/16" x 25'
CNC-625 = 3/8" x 25'

I think you'll find that most parts stores just slap a sticker with their own logo over the supplier's label. Some will go as far to assign their own unique part for inventory control and point-of-sale systems, but they should be able to cross-reference the CNC #s.

Yes, the copper-nickel tubing uses the same tube fittings as steel lines. New inverted flare nuts are available in short and long varieties; here are the supplier (Edelmann) part numbers:

121003 = 3/16" short
121030 = 3/16" long
121004 = 1/4" short
121040 = 1/4" long
121005 = 5/16" short
121050 = 5/16" long
121006 = 3/8" short
121060 = 3/8" long

...but I've never run across a long fitting used on an OE line.

Nope, no proportioning valves used back then.
