Just today found out that mine is pretty beat up as well. Probably need to find a better one.
One thing that's a bit odd that there was a vertical plastic "can" attached to it and I always thought it was a Ty original until it started to come loose and when I checked it was't visible in any other stock engine bay pictures. It has a number on it and googling it says that it is a "RESONATOR. Air Cleaner Intake. This genuine part fits your 1991 Buick Regal., #14 in the pic. Wonder what was the idea to have that?
You can see it there between ABS and brake fluid reservoir:
