sheetmetal disc under pedal box Options

[lkeigwin]

Does anyone know the purpose of the sheet metal disc, about the size of a half dollar, that I found under pedal box in my 1975 1.8? I've seen reference to it here only once before, but no no said why these are found in some cars at least.

Thanks, Lloyd Keigwin

I think you are referring to the welding access holes in the chassis...
in the rear trunk too.

for the long arms of a spot welder to reach through the hole and allow access for the spot welding

thanks Brant but I think this piece (55mm) is bigger than the holes you're referring to. And of course it is not a hole, but what you get when you cut a hole. I should note that there is no serious rust and that I think I'm the first to mess with the pedal box. Nearby there is that curious cut out in the sheet metal plate below the floor (looks like a weak and misplaced tow hook) but I found this disc on the inside, under the pedal box. Up toward the front there is a lot of seam sealer and it's easy to see this piece was pressed in. So I'm thinking this was meant to spread the load from the pedal box, or maybe to keep the box from being glued in by the seam sealer. Or maybe Jurgen was just funnin' with me 49 years ago when he threw a piece of scrap into the footwell.
