Need a replacement window latch, SUNAIR Aluminum Corporation

A quick learner from Simi Valley, California says:
My condo was built in 1988 and one of the black window latches broke off the window. It was the only window that does not have an outside awning or patio cover and tends to get rain directly hitting the glass when it does rain in southern California. The metal looked corroded.

Would you please help me identify what part i need to order to replace it?

Please see our 90-005 lock, this appears to be a close match.
