From the engine bay looking toward the DS footbox.

That gap does seem a little wider than I've experienced. If you're positive the panel(s) are properly positioned and it's not going to get any better, probably going to need some fill pieces from aluminum. I've seen some guys do that. Or you might get away with a couple layers of aluminum tape. The ones I've done were sitting down more on the tube and I used a bead of structural epoxy on each side.

Just a constructive hint FWIW. I'd recommend trying to clean up the silicone a little better than showing in the pictures. Once you place the panel and pull the rivets, try to get all the squeeze-out cleaned up. That stuff is nasty and not much is going to stick to it. Plus just looks neater.
