you know a simple removal and a quick sand down, 2 rattle cans - 1 primer - 1 in gloss black and you got the originals in gloss black so no fitment headaches and no need to buy anything else... if you want to be fancy you can add some lacquer on top of it but imho there is absolutely no need for it. It does give it more protection though... and i have done this before long lasting without the use of primer and lacquer.
It all depends on how quick you want it done....and if you got the stuff laying about as the end result will be exactly the same... the rear one is a bit harder to put back but it can be put back with 3M double sided car tape... just cut as needed.
or you spend money buying replacements...
