Is this engine all original?

When I see Pic's like them shown it kinda piss's me off that some one could let them go that bad, people that live around me think I'm nuts because I always kept my cars in-out-inside etc clean.
 
Think I just barely saved this one even though it been in a garage since 1993. I pulled the entire interior and have cleaned every peice one at a time. Por 15 all the metal and trunk. Thankfully there was no rust. I hate T top cars.
