Wolf Walker from the site here came by and helped me diagnose the problem. We went driving and when I applied the parking brake while my foot was still on the gas, the mystery noise became very loud.

I definitely am going to have to replace the parking brake shoes. Hope there was no damage to the drum. We loosened the parking brake cable which was maxed out to let the pressure off. Will test drive in a little bit and see if that temporary fix worked till I can get the parts.
