Hey Dave,
Thanks for the kind words, it seems like ages since I started this and I am wrapped that it's finished.
Look forward to reading yours, and others threads, when you do your swaps, In hindsight it was a bigger job than I first expected, but I think you just need to be patient and spend the time documenting the pull down to make the rebuild more enjoyable.
Couple of things I thought I should add, I stuck adhesive Mylar down on the pop bumpers, don't notice it and the ball gets a serious workout in that area.
Make sure you invest in a contact adjuster if don't already have one, best $6 I've spent.
I had a blinder of a game this arvo, 687,800, high score with all settings standard.
I've been playing my Black Knight full on for over a year and still have not beaten the default high score of 2,000,000..
