I've searched high and low for this piece. I would prefer a new one, but I may need to settle for a nice used one. Let me know, thanks

I think I have one will look tomorrow when I get off work

Sweet, let me know.

Sorry no joy don't have one. I will keep and eye out for one

Maybe,

Shows two who claim to have it.

There's one on eBay right now, NOS piece.

Can't locate it on eBay, what words were you using? If you see it can you shoot me an item number, thanks. Be stoked to find a new one.

All I did was search parts for my ear car, 1985. Then it took me like an hour to go through each and every part for my car. That's how I found it. If I stumble across it again I will post the link, but I have things to do and places to see.

I found this is five minutes.....

Edit. It's not the same part number you're looking for.

I have one off a 1991 RS. It's not perfect though.

I found 30 of those, that's not it.

The one I'm looking for bolts to the bottom of the spoiler, back to the core support I think, may be called a air baffle too, Ive seen it called both.

This oemcats place lets you put it in a cart, but there's no way to check out. Tried for a half hour, it finally said call about availability, don't think they have it either.

I was trying to remember the part # earlier...I'll check what deflector stuff I have tomorrow.

That would be great. Hard to believe there's not a NOS piece somewhere, but I can see it being a part that gets pretty hammered.
