Did the stern siderails fit without modification?

Hi John

The actual Stern rails themselves screw on without any modification (using the flipper buttons for alignment in the existing rail holes)
However, this leaves a small gap of about 1/8" between the plastic glass guide and the rail itself at the front of the machine. This gap tapers off to nil at the backbox end. I found the gap virtually unnoticeable when the glass is installed.
N.B. To successfully fit the lockdown bar, I found it necessary to judiciously cut & file about 1/8" steel out of the two "tongues" that go down through the lockdown mechanism. This overcame the extra 1/8" spacing problem & works perfectly.
The only way I can see around this method would be to re-position the flipper button holes on the cabinet, this struck me as too much trouble.

Hope this answers your question.
