Sill covers

My sill covers and the polished plate are well scratched. I’ve seen that MX5 parts do a set of genuine Mazda ones (sadly with Roadster on rather than MX5). comments suggest that fitting them is quite easy. Has any one fitted these? How do you remove the old ones please?
Many thanks Steve

They just pull off upwards.
Be careful with this cold weather, I had a plastic clip break.

Thanks for that, I’ll wait until the warmer weather.
