1968 Dart GTS Convertible project

I am looking at this Dart GTS as my next project car. I am a B body guy, this would be my first A Body if it comes home with me. Before I get serious about doing it I need to know more about this model car, it's real world value as a finished car, GTS rarity and how to tell if it is a real GTS. And any other valuable 68 Dart info.

Description;
1968 dodge dart GTS convertible project car. An original 340/automatic gts. Was a nice running and driving car before restoration started. Have basically all the parts and over $65k invested to this point. Basically mostly all new sheet Metal, almost no Miles on rebuilt 383 with a mild cam. Had a manual transmission but was going to put a correct automatic back in. Many parts still new in box. 90% of body work done and all panels fit perfectly to the car. I have all the parts and it’s basically pretty complete.

Some pictures of the car:
