The title pretty much sums up the post. Got a Black Pyramid last year, and the previous owners had what was basically desk chair rollers on it instead of levellers. Bought some levellers from Pinballlife a while ago for spares, and they don't thread into the legs.
Wrong legs? Did Bally use different sized thread on their levellers?
Also, unrelated, but can someone share a shot of the drop targets? I think i have the wrong ones in mine.
