I'm doing the bodywork on my 260, finally got around to the rear. The lower valance panel has a factory hole on the left side, directly below the reverse light, app. 5" x 1 1/2" I'm curious what is the function of this hole? My 240 has no hole & in the dim recesses of my memory, it seems as if 280s had more than one.

Also, I want to clean up the area behind the bumper & put 240 bumpers on it eventually, What is the best method of filling the recessed area, behind the bumper, that is dotted with welds & holes. Seal it up & weld a piece over it or fill it with a fiberglass product. I'm thinking layers of mat and cloth or stranded jelly. I'm open to any suggestions.

Thanks

Why do you want to fill this area that will be covered by the bumper?

I filled mine with FG mat and then smoothed with bondo.

But I have no bumper:)

The bumper will come later, maybe. This is a case of "as long as i'm in here". Any cracks in the FG or bondo over time? This spot on the body seems like it is one of the few areas that don't have much flex in it.

Any idea what the hole in the rear valance is for?
