Looking for a OEM tripod foot for my EF 400mm f2.8L IS USM

Well, it seems that you likely have 2 choices:

1. Live with it. It looks like the cover is a simple friction fit and another could go the way of the original. Think of it as "now my lens won't lose any more parts."

2. Make the lens more functional with a good 3rd party replacement foot like this:

and save your original foot so you can admire Canon's OEM expertise. In my experience, replacing the foot with one that incorporates an Arca mount is much more useful than adding an Arca plate to the OEM foot. It's more comfortable and secure to carry and has a lower center-of-gravity (is more compact).

Like Chesapeake, I've replaced all of my big white feet with ones like the above. All of them give me a more secure mount than I had when adding an Arca plate to the OEM foot.

But, heck; if you prefer looks over functionality, it's your lens after all...

It appears to be beyond your comprehension that someone would want something to be original!

Well, actually yes. First I can't comprehend why Canon refuses to jump on the Arca Swiss bandwagon.  It's nuts to require an aftermarket Arca Swiss plate to be screwed onto the generic Canon plate when Canon could very easily make the foot Arca Swiss compatible in the first place. Call it "Canon Dove Tail" or something if they don't want to use "Arca Swiss."

Beyond that, unless you bought the lens as an investment or to be a museum piece, the only circumstance where it would not be better to add the replacement Arca Swiss foot is if you never ever use a tripod or monopod. To each his own, but you saying you "want something to be original" in this context makes as much sense, if you plan to actually use the lens, as if you said you don't use any camera settings other than full automatic because you want the camera to stay original.

I have no idea what Canon charges for a replacement OEM foot, but it is probably outrageously expensive. If you are dead set against an aftermarket replacement foot, I would buy one anyway and offer to trade it to someone who still has the original.
