Need help with a replacement tilt window pivot lock shoe

A handy person from New Jersey says:

I believe the window is made by Great Lakes. The inside of the window shoe slot dimension is approximately 1/2" x 1-1/4". I am not sure of the shoe height. I cut a piece of cardboard to that dimension and inserted it into the shoe slot. It leaves about 1/8" or 1/16" space on all sides. I did not take the old shoe out at this point. What should my next step be to confirm? Can you point me to potential shoe options? Send any questions. I appreciate the help. Thank you - John

Based on your dimensions and photos, your shoe may be a match for our 15-188. I highly recommend removing yours from the window to confirm that your measurements are accurate, though. Take it from me, it's better to be safe than sorry. Measuring a shoe while it's still in the window is basically a coin flip as to whether you're accurate or not. Better not to leave it to chance.
