My Dad left me a yellow 67 rust bucket :)

My father passed away a few years ago, leaving me a beautifully sentimental car. His 67 Mustang hardtop coupe !!! I have a very basic understanding of cars and a solid set of tools in a 2 car garage with limited space. The car has been rebuilt twice (i believe) and I'm not %100 certain of any of the technical names or profiles of the powertrain. Hoping for some insight toward making my first moves on the car. my aim is to make it a weekend delight/nightmare
I'm excited to learn what I can about the car.
To those who read this, thanks for the welcome I love you <3
