I've just spent the last 1 1/2 hours shearing posts and tearing out T nuts while stripping my BK2K. And I've only got as far as slingshots and inlane guides. Every T nut spinning and when gripped ( which is a job in itself ) the post/machine bolt shearing because some idiot has loctited everything! And it looks like it's going to be EVERY post. The joys of pinball restoration.
