Uniframe Replacement Window Parts

A quick learner from US says:
I'm Looking for tilt latch buttons for Uniframe windows.
These are not surface mount and the "prong" on them that attached to the internal mechanism has broken off. Hopefully new can just snap back in. (?)

Also looking for the plastic trim piece for the bottom of the upper window which also has the 2 connecting snap "prongs" broken off.

These are for windows in my parents house. What other information might u need for replacement parts and i will try to get the info from them. There are no identifying numbers on them that i could see.

Looks like your tilt latch has broken, but I'm not sure what it is. Do you have an undamaged one we can look at? If possible, I'd like to see it out of the window entirely. As for the trim, can you show me a clear picture of its end profile?
