what if you build a cover the same basic shape as the existing depressed part of the firewall, just a smaller size but in scale and centered to the existing depression, and make it tall enough to pull the dizzy out if required. leave a flat flange around the outside edge for attaching, possibly with a small lip around the edge for strength, similar to a diff cover. cut the firewall hole smaller than the new cover, obviously, and then bolt the cover on from the engine side of the firewall to make it easier to access. a corresponding removable flap would be needed in the floor covering inside but that part isn't built yet anyway.
just a thought that would save you redoing a bunch of bodywork
