Data plate location

[Bruce]

I was looking for my data plate on my 79 ECA any suggestions where to find it? Not on tail, not by rotating beacon, and can't find it in side. Thanks for any help.

Mine is screwed into the floorboard on the left side about 20 inches rear of the back rudder pedals. It’s a 67 so not sure if it’s changed.

That is where mine is located as well. It is a 75

You were right rear seat left side was covered in dirt. Thanks
