I have a Unique Cobra with a soft top and side curtains. I have no idea if it would fit your car, but if it does, Unique offers a complete soft top with side curtains for $1,995

I live in Lawton OK (about 3 hours from Dallas). If you ever want to make a road trip up, we can temporaly take the stay support mounts and windsheid clips off my car and put them on yours to see how well it fits.
