Unless you buy an Access Norton membership, which allows easy image posting, you need a host site you can upload your images to, and then point to them via a URL. If none of that host site URL talk makes sense, buy a Access Norton membership if you want to post images.

If you post an image, someone will know what tail light lens you need, or at least know where you should start researching it.

Old britts is a great source for quality parts in US.
Maybe #36 on this diagram for fastback.

Welcome.
A word to the wise, get a clear title in your hand before investing more money and time than you can afford to forfeit.
