fixed it wasn't as bad as I thought
Luckly the radio mounts to a plastic plate secured with 4 screws to the microwave cabinet, pulled the 4 screws, pulled the plastic plate and re attavhed the metal sleve more securily to the plastic plate, pulled the radio out of the sleve and reattached the trim plate back on to the radio, apparently the trim keeps the radio from falling into the sleve like it did. I also added some electrical tape to the plastic tabs to keep the trim plate more secure, if it vomes off again I'll reattack with some epoxy. All is well now that I spent a few hours checking operation of the various things like the sink, shower, fridge, A/C, stove, I'll have to
do a one night trial run camping in the driveway to run things.
