Cut opening for the MGL V10 comm radio. Installed 6-32 nut plates behind the radio mounting holes. Finished opening size for the KX-76A so the transponder slides in/out without catching on the panel edges. Received the Hella fuse blocks from Summit Racing. Checked them for fit in the space under the panel where I intended for the fuse panel. The Hella fuse blocks may not fit either. Exploring other locations.
