Hey John!

The # Replacement Black Trim Kit # Trim-BL-FR03 is indeed the correct trim kit for Greystone microwaves such as Greystone Built-In RV Microwave - 900 Watts - 0.9 Cu Ft - Black # GR67FR, and it can be found with the trim in this kit # 324-000105.

It has the following specs:
Dimensions: 23-3/8" wide x 15" tall
Mounting holes: 22-1/4" wide x 12-1/4" tall

Your cabinet is a tiny bit taller (about an inch" so you may want to shim it and add a little filler cabinet wood so you don't have weird gab. Then you may need to trim width wise just ever so slightly. Unfortunately this is fairly common in the RV world.

You may be better off with the High Pointe Built-In RV Convection Microwave # HP99ZR which comes with black trim kit and fits cutout of 22-7/16" wide x 15-3/16" tall x 19-1/4" deep.

Let me know what you think!
