I have a trim kit for an old GE Profile microwave. This is the kit used to install a microwave into the kitchen cabinets. This is an old (~ 10 yrs old) model and is discontinued. The trimkit model number is JX827SMSS. It was used to install microwave model PEM31SMSS.
I have all the parts except the two base support brackets. You could probably find something to use at Home Depot.
