shore power cable route alternative?

[JRF0st3r]

Our '67 Safari, like others I have seen on this site, has a notch in the rear access panel to allow connection of cable to shore power. Although we are getting a new access hatch, it will not come with this notch and I hate to cut into the perimeter extrusion and create a mouse hole. Is there a reasonable alternative?

On 68's the cord passes through a hole in the floor right under the breaker box which is mounted on the rear wall just inside the hatch on the right side. The cable comes out in the bumper trunk and is stored in there. There are actually hooks on the bottom side of the bumper trunk lid that are for winding the chord. I don't use them as there is plenty of room for the sewer hose and chord. I could send pics if you need them.
