According to the VIN you have a 7 1/4" rear end (G 31:cool:. They don't last too long behind a 360. Pull the cover on the rear end and check for bits of metal and chunks of teeth. How do the spider gears look? If you are lucky all you will find is shiny gear oil. I had a '77 Roadrunner (318/ 7 1/4") that started making the sounds you are describing. Listened to it for a couple of weeks until I heard a loud bang while pulling out of a gas station and the car quit moving.

G - vin and fender are above

The rear end is identified on the fender tag not the VIN. The VIN tells the original engine size. With these cars being nearly 40 years old there is no telling what might have been changed over the years. If it is a Mopar rear end and you have 9 bolts on the rear end cover than it is a 7 1/4, 10 bolts would be an 8 1/4 and no bolts would mean it has been upgraded to an 8 3/4.
