Welcome to the group Sully. I for one would love to see some pictures of your car. Here is a little info I have saved from a post on the barracuda owners group that you may find helpful. The outer wheelhouses are not available. At one time they did make them but from what I heard the quality and fit was very poor and they discontinued them. Your only option at this time is to find some off a parts car or fab them yourself. The convertible specific partts will also have to come from a parts car or be fabbed. As for the trunk extentions see below.

"Dart/Duster trunk extensions are the correct length, just
too wide on the aft end. I modified by taking a pie shape
cut out, front to back. Have heard of cutting along one edge
and removing material. That leaves only one weld seam."
