Hi Melvin
It sounds to me like you are on the right track on narrowing down what is contained in the back.
Just one thing. You call it unclassified. You do mean classified right ;o)?

[Take a look at this pic...
Go to http://www.mindef.gov.sg/rsaf
then click "The News Hub"...after you have entered the page, click on "The News, Etc"
Then u will see the "Wild Weasel" F-16C/D with a special structure on its back. This is the Wild Weasel equipment.
This is believed to contain unclassiied electronics, special jammer and weapon delivery system for SEAD mission.
This may help your research in the special F-16 package. I'm still reseaching though, and no military source is willing to give me more information of this equipment.]
