    I haven't made it through the entire thread yet, but wow! Nice job and great score. I like the trick with the drill to clean out the old cans. I have used a screwdriver, and tried the boiling water trick too. After those I try to just mount the new caps underneath. I see that wouldn't work for you, though.

    Anyway, well done.
