Searching for keyed mortice double latch

A quick learner says:
The latch fell out of my Jeldwen door handle and I tried to re-install after watching your vidoe. The latch will not stay in. I understand I may need to replace the entire mortice lock but cannot find the one I need on your website. It is a double-pronged keyed lock. It 12 inches long.

Hello,

Take a look and compare the specifications of the 82-265 mortise lock and 82-086 handle set with 3-15/16" hole spacing to your original hardware. Thanks for posting!
