wow, those came out great! I worked for Bear / Spx Corp as a field tech back in the mid-late 90s

I have started restoring a Bear Headlight Tester Model No. 560. I have two questions: (1) There is a small "pin" which is in the side of the optical unit's frame which slides up and down on the chrome bars. On the frame I have, one of the pins penetrates through the sidewall of the tube such that I cannot insert the chrome bar through the tube on that side. Only one of the tubes has this condition. Please see photos 1 through 5. Is there a way to push that pin back through the wall of the tube so that I can slip the chrome bar through it? (2) The small viewing window on top of the optical unit was damaged during shipping due to poor packaging. Is there a way to remove it and install a new window? Does anyone know where to obtain that small glass panel to replace the broken one? Please see photo 6. Thanks!
