1973 Dart H Code value

The roof, by far
Most of the guys on here can swap out an engine with regular hand tools in an afternoon

But a roof?
Now we're talking welders and paint
Not as easy to swap out

I'm not worried about doing the swap, that is no big deal. My concern is more about what it does to the value of the car. Would it actually take away from the value putting a factory "sun roof" top back on it in contrast to a "Non-Sun Roof" top?
