OTOH, with the G63's entirely different BB, once it is removed (in 5 minutes time), the stock OEM MB cover plates (same as used in the Euro 2019 G63's) will 100% cover the exposed opening in the front of the bumper slots. The MY2019 G63 uses an entirely different BB. Thankfully, it will not leave any exposed holes/openings on the TOP section of its bumper (e.g., the “top section,” meaning the part of the bumper that is parallel to the deck) when the G63 BB is removed and summarily ****kanned (or, unloaded on eBay!). I plan to immediately remove the BB on my G63 Day 1 (hopefully via MB Service, if they are willing to do this in the first place, which I doubt), unless I get a MY2020 G63. In the latter case, who knows if MB will stick with the current (horrible) version(s) of the BB(s). IMHO, the 2019 BB's (both models) look like a Rube Goldberg last minute rush job (e.g., even blocking the non-existent camera on the 550, thus eliminating it. How stupid!) to get the cars out the door to the holding lots, with the first MY2019 G63’s rusting for up to 6 months “at the docks.” With any luck, perhaps MB will redesign the MY2020 BB, at least for the G63 (plus, implement MBUX!). Anyways, I plan to use the bumper's front face opening (without the cover plate) on the passenger side, so I can have a fabrication shop custom design, build/fabricate, and weld-up, a nice front mount for my Icom AH-740 HF antenna that will bolt into the female threads of the BB’s mounting point on the passenger side. I will then cover whatever is left, as necessary. This opening will be so perfect for what I'm trying to do with mounting an HF antenna on a G63. Probably the first HF application on a G63, outside of the G-Pro line, and military G's, of course.
