There is a special threaded nut inside the latch mechanism, that has a double start thread. That's called a barrel nut.
The rest of the 66, 67 and 68 latch mechanism has not been available for decades because of the cost of tooling to make those parts.
Tooling costs must be recovered in the sales of anything.
That's just not going to happen with that latch mechanism.
