Yes M body one has metal backing too. I think one could be modified to work but would be alot nicer to have the right one. Sent you a PMI suspect it is. Even if it's a diplomat filler, the two are so close it wouldn't take much modification to fit them. It mounts with a metal strip to the bottom of the grille, same as my Aspen. I sent an offer for it, need to get some TT4 color match paint as well
That's the spirit. Besides, the color match won't match anyways because of decades of sun fadeI ordered the part, it's supposed to be here Friday. I ended up getting $50 off the asking price. I'll post pictures when I get it installed. I'm not going to get the color match "natural suede tan" paint at the exorbitant cost, I'll just go to the store and find the closest shade of beige spray paint I can and call it good.
