I have new Raybestos calipers, hoses and banjo bolts on the rear of my '67 that were leaking at the hose/banjo bolt. I don't think the calipers have concentric grooves in the hose recess for sealing the crush washer. The hose fittings do have the concentric rings. I tightened and reseated the copper washers a few times and got the RH side to stop leaking, but I'm still getting a very slight leak on the LH caliper. After a few hours I get a drop of brake fluid on my finger when touching the banjo bolt. Today I plan to replace the copper washers with a pair of Murray 5/16" ID A/C sealing washers (P/N 24401). I've read that these A/C washers will seal leaks when plain crush washers won't. These are similar to the Earl's Performance Stat-O-Seals with an o-ring mated to an aluminum crush washer (P/N 178005ERL). The Murray washers were all I could find locally and are cheaper at $1.79 each. It may be a good idea to have a few of these on hand, or just use in place of copper washers.
