Acorn Window Pivot

This is the same kind of corner pin I have and I can't find a replacement. Here are some more photos of what it looks like. There's a long screw that goes all the way down into the side of the frame. Any help finding this would be wonderful.

Greetings, this is a storm window top tilt pin similar to a tilt key, only without the right angle part that is anchored in the corner of the frame. Instead, it slides into a track along the top of the window frame and can be replaced without taking the frame apart. Unfortunately they can also slide ... (cont.)

Trying to locate this corner

I am trying to locate a replacement pivot for a residential storm window. It is for the opposite end from the one pictured so the pin would face opposite direction. I do not have a manufacture name. I could not get your part

Do you have these plastic clips which keep the storm window in its tracks? Both of these are broken but the bottom one is still serviceableThanks for any help you can giveChuck M
