Appreciate all the replies so far!
So I was able to remove my current plexi set with no problems, however, even before removing them the printed graphic on the back is both scratched in a few places and severely faded.
I actually ordered a set from yaton/ebay link a few weeks ago and waiting for it to arrive.. however I have little faith its going to be in any better condition that what i have now, so I have already mentally decided that whatever comes is most likely going to be a worst case scenario spare for my machine or another.
Sheep, do any of the extras have, are the graphic still vibrant with the pink stripes and yellow/green astro city in the middle (most all have faded to being white.)
