Installed the lock cam rollers and had a few issues. When drilling one of the rivnut holes the bit grabbed and the hole ended up about 1-2 mm lower. I installed the 5mm rivnuts with ' J-B Weld ' for extra strength. After thinking all night of how to fix the issue of the lower rivnut, my only option I could see was to dremel the door latch lower. ( seems to have worked OK ) The doors locks were tighter than I was comfortable with, so I removed the brass bushes and the doors now close much better. If the door rubber settles over time I will be able the slip the bushes on to take up any future slack.
