Can't say for sure if it is the same but my 78 was making a "metal rubbing" sound everytime I moved the car in forward or reverse... It was coming from the right rear... I jacked the car up and could not see a darn thing that looked like it should be making noise when I spun the wheel by hand... I pulled the rotor off & found that one for the parking brake springs had broke on one end and had worked it's way between the brake shoe and the rotor... "No-more noise"

Quite often it’s the parking brake hardware. A spring will break inside and drop down and rub the brake rotor.
This sound is nothing to fool around with though. It’s getting warmer outside and people are driving the cars with the windows down and the tops out!
Other things to check: Rear wheel bearing clearance, U-joints and as mentioned above the parking brake cable rubbing.

Hey like Choppahead said have you tried the GM lube and the rear end oil change ? it will make a noise like Something in the drive shaft My 77 use to do it after I would get the rear end up to temp the back end would start cherning like it was mixing somthing up back there,did the rear end grease and the 2-Bottles of special lube and presto the clutches in the rear end turned fine and never made the noise again .do the easy things FIRST.
