'68 Roadrunner help needed in Montclair, NJ.....ASAP!

Hello all, I've been a member here for quite some time, but mainly as a spectator. I'm located in Pittsburgh, Pa. and my brother is in Montclair, NJ, 07043. He just contacted me and his '68 RR won't start, although it started/ran/drove before being parked. I tried to diagnose it via the phone, and it's tough as he's there by himself. I'm looking for someone in the N.NJ area that could help him out. I don't think it's anything major, as it has battery power and cranks. It should be either ignition or fuel. I usually work on his cars, but I'm not there. If someone that is familiar with these cars is available, and could help, I'd appreciate it. The car is a restored '68 RR, 383/auto. Stock, should be a simple fix. I'd appreciate anyone that could lend a hand. Please let me know asap, thanks in advance.
