It seems you have already done it.
Ok, the exact dimensions...
What are the dimensions and the position of the fin tab from the fin root?
You might draw a rectangle wth according size on a new layer and then move it to the right position. Then take the whole as a background for a new drawing on a new layer. Or...or....So many ways and a lot of explaining cad basics to a newbie.

You could provide the file here with "More v" and specify dimensions and the position of the fin tab.
Probably easier than explaining a lot.
