Do you have a picture of the one you have? I have a 73 FST model. It had hard doors on it when I bought but included the soft doors. Don't see any difference than those on my 68 and 70 FHT models.
Here are a couple pictures. The bright shiney one is a regular door stop, more weathered one is a FST door stop. They have about same bend but look to be about 1” longer than hard top.
