I didn't do any housing mods, personally. Daryl at AA transaxle took care of
all that. It's just a recycled housing from a syncro tranny, I believe.

The way the Diff lock works is that there's a "button" on the outside of the
housing, fore of the starter. Push the button in to turn on the locker, out
is off. I bought the factory vacuum actuator from Derek Drew (about $75).
Its connected to the "button" via a pin, and pushes it in or out when vacuum
is applied to one of two ports. I think you would be hard pressed to make it
work with a cable - you wouldn't be able to make it push the "button" in. I
wish I had taken some pictures during the install, but alas, I didn't. Maybe
some pics of the vacuum valves someday...

Other than this "button", there's really no difference between the housings
for the transmissions. For those asking about this option in an automatic,
I'd have no idea, you'd have to ask for Daryl - who was very helpful, I
would recommend him without reservations.
