Hi, whilst I wait for my GX to arrive I am buying all the small items that I won’t be buying from the dealer, one item is the tow hitch, can someone that has a GX send me the box length of the rear trawler hitch hole, I think it might be 40mm by 40mm but if someone can confirm this please I would appreciate it. It might be slightly wider to allow for a standard hitch of 40mm by 40mm to fit in.
