Well I figured this out and it was easier than expected.  On my unit, turned out the internal antenna perfectly covered 2 screws on each side that held the handle hold-downs in place.  Pretty obvious once I carefully pulled back the antenna.  I was concerned about damaging the antenna so was reluctant to pull it back.  But by removing all the small nails holding it in place, I could slide it front to back carefully and remove the screws to release the handle hold-downs, allowing me to replace the handle.  Seems pretty clear now that I know, just figured I would post this update in case someone else struggles with it in the future.
