In the last week or so, I repaired the worn slots in the rest of the door latches. The next step is to repair some worn spots on the main latch bodies and put everything back together. I still need to find or make the correct rivets that go through the slots.
I also fitted the wooden roof ribs. They needed a bit of trimming to fit up nicely with the wood around the edge of the roof opening. I also had to drill some holes for attaching the wood blocks that hold the sun visors. When it is a bit warmer, I can put a coat of varnish on them and they will be ready for installation.
