Goody,
I think the spoiler would look great on your car! It is hit or miss with the deck lid. A 72 should not have the cut outs but you never know. My 73 did have the cut out or some one changed out the deck lid but that was unlikely as I bought the car in 83. By the way, I have not forgotten to get you those firewall pictures but I have just gotten back to the states after being gone for 6 weeks.
