Hey mate i'll try and help.
The rear quarters
You need to take out the rear bench, the base lifts up with an almighty tug but before doing that remove the plastic isofix clips at the back these kind of pull up and twist.
you want to take out the kick strip that also runs along the front sill and into the rear quarter along the bottom again no screws just clipped down (it will feel like your going to break it pulling on it, but it'll release before it does)
The b pillar needs removing which remove the little airbag badge with a pic of small flat blade i found going from the bottom of the badge worked best.
Then in the hole there is a torx 20/25 i can't remeber off the top of my head,it's to early lol.
I removed this completly and took the b pillar of the seat belt but for this you will need a spline drive (like a torx but more splines lol)
Again i removed the rear seat belt with a spline drive to get this out of the way, I'm not totally sure this is essential but just makes life easier not battling with bits in the way.
Then if you drop the rear bench behind where the seat latch is theres a little plastic panel which you need to pop off and again there is 2 torx just there one direcetly in veiw and another one deeper in the whole, (if i rember correctly the one deeper in the hole is for the c pillar not the quarter)
Then you should be good to go. Again These are so well held on it will feel like your going to break the side of your car off, ( i know people who have trimmed the inserts inside the car because they can't pull these quarters off lmao)
This should give you something to go off if you get stuck on any part of it drop me a pm and i'll go take some pictures and try guide you through anything else you need.
Also if you need any help on the front doors still give me a shout mate.
