Top Frame Help??

Yes Dart and Barracuda is the same, but good luck finding a rust-free one. I recently parted out a top and sold the header panel. It had minimal rust and I got $300 for it. ALL of the rust, most are rusted through. I can see if I have another one, but it is getting to the point that they are getting hard to find, so I don't know if I should part another top frame out. Nobody makes them.
