I’ve made a good start on the C pilar prep, starting with cutting the outer arch off; I need to repair the bottom of the sliding door seal channel and need to trial fit the new outer arch to make sure it fits properly.

The inner arch isn’t in too bad condition, with the majority of the lip looking to be usable, I’ll just need to repair the ends of it:

The rear corner however has an impressive amount of filler and fibreglass in it!

I spent a good few hours trimming the new outer arch to the correct size to get a really good fit (the channel needs more work though):

Lines up with the door pretty well:

And looks bang on to me:

I’ve started fabricating repairs for the inner part of the C pillar:

And the strengthening plate that covers the C pillar (the new one, template and old one):

I’m aiming to get the C pillar finished this week.
