Even with the bark the point should be easy to find. Just look for the "hump" in the brisket. Use a knife to prod around, in order to find the fat vein. Once you find the fat vein, use the knife and follow it; keeping the knife Pharrell to the flat.
As manfromplaid stated you can make burnt ends at any time. It now may be easier to make the burnt ends in your kitchen oven, now that you already have a nice smoke flavor on the brisket. After cubing and saucing the meat, place on a baking sheet or foil pan, cover with foil, and follow your recipe for burnt ends. I like to use an oven temperature of 275°F. Though the point is traditionally used for burnt ends, I like using the flat.
