Part 2456 - 6x14 Dark Red Plate, made up of 2x smaller dark red plates, doesn't. Weaken model and is underneath so cant see. Part 4095 - 6.6l bar replaced with 6l bar. Part 47996 - Light bluish grey rigging on rear, replaced with black (my opinion this looks a lot better and stands out). Part 50990pb03 - Radar dish, original part with water transfer, looks amazing and closest to printed dish i could find.
Part 30365 - Light Bluish Grey - Light Grey. Part 4592c05 - Grey Lever - Replaced with Grey base, black arm lever (looks nice as breaks up the grey). Part 75535 - replaced with Part 62462. Part 4599a - Tap with hole used instead, cant really tell unless looking increasingly close, mixture of hole and not.
All the above parts have been done due to availability of them, but nothing distracts from the overall look and in my opinion some of the changes suit the model better as there is a lot of grey involved, 99% of parts are new either from Bricklink suppliers or direct from Lego. Also has the UCS display plate with a custom printed glossy sticker to display with it. Need to make very clear, this was custom build so does not have any stickers (apart from UCS Plate), no minifigures, no box or instructions, these are easy and free to find on the internet, but made from 100% original lego parts and 99% new elements.
