Farley Double Hung Tilt-in Windows

I needs parts for my Farley Double Hung tip-in windows. See the attached photos. You will notice the broken peg in the first photo and the broken piece is still in the mechanism. What are the parts I will need? Are the parts specific for the right hand and left hand sides of the window? Will I need any specialized tools to complete the repair? I've not yet attempted to remove the broken peg from the mechanism. Any tips on accomplishing this without ruining the mechanism?

Thank you,
Paul

Thanks for the response. Here's a better photo of the part. The overall length is 2 3/8". It is 3/8" from the end of the pivot to the flared part. The 1st hole is 15/16" from the end of the pivot and another 1 3/16" to the next hole.

Thanks for the help.
