The Rad Rubber pieces are this has and fit well covering the opening well. My 80 was missing one pice when I bought it and the others had some torn out mount holes so I ordered these.
I just ran the part numbers and the Toyota aprons are cheaper than the Rad Rubber if you get them online.
Sometimes it’s easier to go over it than break out the saw. Some of the “roads” in that forest have gone so long with out use that I’d have the saw out 9 of every ten minutes. That’s when I start pushing through instead.
