67 plymouth barracuda fastback 273/727

I have had this car for twenty years, it hasn't been on the road in fifteen, It hasn't always been easy to hold on to this car or find places to keep it. but i managed to do it. Today is the first day of my rebuild of this car.Not sure where this project is going to lead me, so many choices on what to do do i keep it original ( its numbers matching) or do i go resto/mod and if i do what should I do. I open to suggestion. Thanks I'm glad i found this forum.
