Thanks Paul, the
26-366 pivot bar looks to be just what I need.
Unfortunately, the two tilt latches you suggested have square ends while the one I seek has one rounded end. What I need looks more like
26-371 but that is 1/2" too short.
26-439 is the right length but is a surface mount, not a snap-in.
26-442 looks like the right shape, and is spring loaded as is the original broken part, but no dimensions are given. I need it to be approximately 2-1/2" long. A picture of the broken latch was included with my original inquiry. This time I've also attached a picture of an unbroken latch in case this helps.
Thanks again for your assistance.
John
