If your careful you won't need the TRT (& Sadly no TPS don't sell these lol!)
It's very easy To remove.
After all the screws are removed, pull the bottom out gently using the door bin, then get your fingures behind the front corner and slowly pull the bottom of the panel both of the sides will pop naturally.
It shouldn't break the clips but if you bust a few it won't stop it re-fixing back on I've done hundreds now
Just remember to reset the open clips ( just push them back together ) before you pop the panel back on
hope this helps you
