Radio Shack High Performance radio.

I'm working on a Radio Shack radio, that is similar to a GE SuperRadio. Mono FM, tuned RF on the AM band, large speaker and uses 6 "D" cells, as well as AC.
I can't for the life of me, remove the back cover to get contact cleaner in the band selector, ETC. I removed every screw, six long ones and a short one in the battery compartment. I even removed the handle screws and the one holding the monopole antenna.
These radios were sold under the Optimus and Radio Shack brands.
