Left and right hand latches needed. Actual overall length of broken pieces pictured vary because they are broken. Overall original length was likely 3-3/4 inch.

Thanks for contacting us. I'm afraid this latch has been discontinued by the manufacturer. Could you possibly use our 91-054 as a substitute? You may need to modify it, but look it over and see what you think.
