It's weird looking at your bulkhead/footwell area having just spent a weekend replacing my A-posts and sills, seems like the A-posts on the CSK were fairly unique. There was certainly a lot less of mine left than there is of yours at the A post section
Your C posts/rear "goal posts" look to be in a bit of a state, might be fun when you come to repairing those!
What's the deal with that exhaust manifold on the N/S, has it been welded back together?!
Looks like you're having fun and making good progress either way.
I have seen those footwell panels for sale but it may have been on ebay, if I come across any on my web-travels I will let you know!
