Full and By,
What did you finally do about your chain plates?
Any more photos?
I also have a Cooper 416 and her chain plates are covered up by some nice carpentry, so I am loathe to break in to look. Thanks for the photo, now I at least know what's in there and that it will be a major deal to replace chain plates.
BTW, I have a little website for Coopers, you will find it at:
