Heat Shield disengage

Is there a way to reattach the heat shield over the exhaust pipe on a 2016 Limited 4Runner?

 

I had a heat shield that rotted out around the bolts and was resting on my exhaust making an awful rattle. I repairs by using the existing bolts but with fender washers so it was holding the shield up on newer, “unrotted”, material. Seems to be holding up for now. This was done on a 2018 ORP

 

That or new shield. Those are about $60.

 

Any chance you know the part #s? I've been searching online and come up pretty dry.

Recently had what I think is the rearmost rot out from the bolts. Pulled it out, looks like an oddly shaped L of sorts with a big R stamped on it. Want to fully replace it, but can't seem to find a darn part number anywhere.

 

I had parts counter guy at the dealer find it. I couldn't locate it either.
