I have one, just not sure if it is for a GTV. This could be left over from a GTV that was parted for my long gone GTV. But might be for an Alfetta or Sport Sedan. No part number on this piece. Maybe you or someone can verify what it fits. A few photos. Also has the rubber gasket in good shape. If interested, PM me.

 

Berlinas had a similar one that is more flat on the face that attaches to the body. I have one if first poster's isn't right.

As I read the first poster is looking for a one piece continuous/molded gasket seal, not a wrap-around gasket that mounts end to end, made from a linear stock.

 

You are correct. The gasket is one piece. I can probably find a suitable linear stock substitute with a little research but only when original cannot be obtained. Thanks!

 

I think the Berlina ones are longer than that for GTV

 

The license plate light assembly in black posted by milanomike would be from either a Berlina 2000 or Alfetta Sedan (75-77) as they are the same. The Sport Sedans (78-80) were the same but did not come with the Alfa Romeo script, as it was placed on the trunk lid instead.

 

GTA Alfa, thanks for the info on the license plate light assembly.
