Attached are photos of the part installed and removed (on 1/10" graph paper). The only marking is a "MDC 5" stamped inside the outline of Texas.
The lock screw holes are 2-1/16" apart, like several of your locks, and the lock is 2-13/16" long and 1-5/16" from front to back.
The keeper is 2-1/4" long, 11/16" wide at the ends and 15/16" wide at the center.
Let me know if you need more photos or information.
