Seats and bumber question

[beanie]

been looking to replace the front seats to an aftermarket version for daily use (obviously going to keep the originals). Any ideas on the best type? .....looking for something that is moderately priced.

Also, any ideas on how to best fill in the license plate holes in the front bumper without re-painting? I was thinking of either black caulking or just getting black headed screws. looking for a good idea

as always, thanks for the help
