Now I see why your restorations turn out so well.....you have 3 hands!
When I first saw your photos on FB of Mark's 70Z I knew I had to step up my own restoration project, especially the interior items. You do it right for sure and thanks for sharing your techniques.
My wiper transmission arms I struggled with whether to drill the rivets but decided to do it the same way you did after spending time looking for the correct rivets and coming up empty.
