The only Vintage Mustangs that received factory louvers were the SportsRoof (fastback) cars beginning in 1969. And the hinges were attached to the roof with screws. It appears that you have an early hardtop and there were never any factory louvers offered. I'm sure JC Whitney sold them and there are some for sale in the classified ads here. Apparently hardtop louvers didn't sell very well and there's none made today.

 

She is a 1970 sportroof, and i figured they were mounts for an after market louver. any idea how they attach? dont want to break the glass trying to remove them.

 

On the louvers I have for my 71 fastback, the metal pieces attach to the glass with doublesided tape i.e like moulding tape. You may be able to get a piece of fishing line under it and loosen it off the glass.

"Louvers come with hardware plates that use double sided tape to attach to the glass. The aluminum louver then attaches to the hardware plate for installation."

 

There is supposed to be a vertical tab that has broken off. The louver had a screw and nut that went through that tab and acted as a pivot for cleaning.

Here's a link to the factory type louver, which had hinges that attached on the roof sheetmetal.

I have the reproduction louvers from NPD installed on my 1970 fastback. It has no tabs at all similar to those in the pictures.

 

Thanks all, I will check today if they are stuck on the glass, that would be easy.
Looking close it appears a tab may have broken off.

2 sided tape, cut the tape and they slipped right out. Also you can tell that a tab had broken off.
Tnx all.
Now I think I'll look for a OEM type set of louvers, any recommendations?

 

See the link in my reply above.

 

The louver kit I bought from NPD is very nice. It fits very well and it looks really good. A guy in my Mustang club put a reproduction louver kit on his 1970 Boss 302. I don't know where he got it, but he's not happy with it. It's "caddywhompus" meaning not square.

One tip: My louver install ended up just a bit too low. I tried to line up the angle of the bottom of the hinges with the angle at the rear of the roof, but it didn't work out. The weatherstripping at the top of the louvers should completely cover the glass and a sliver of glass is not covered on my car.

 

FWIW, the only factory-original-style reproduction louver kit out there on the market is ours (NPD), it is our kit, our tooling. We sell them directly, as well as wholesaling them to the rest of the market. Some of our competitors re-package everything to eliminate any signs of "NPD" on the kit, but rest assured, it's our kit.
