Read the security questions closely. Some will say "Have you EVER", others may want to know if you have ever in the last 7-10 years.
Definitely disclose everything. Even if they ask for last 7, and it was 20 years ago, if you list it, they can choose to not worry about it because it was outside of their required parameters.
Look for a reply from our Subject Mater Expert, "Graphic", he is the authority on this matter, and I'm sure he will reply soon.
