Does anyone know what this is off of? I was told it isn't original to this Land Cruiser. Thanks

That vacuum hose should be attached to make the booster work. It would take some pedal force to stop the way it is now.
I'm guessing the diaphragm has failed based on the plugged vacuum line. A new booster would be an improvement on a couple levels.

The OP may be correct, that booster/cylinder was not original on that truck.

It looks to me like the firewall stiffener below the booster has been cut off to allow the booster to fit.

The stiffener has a return where it would have been "cut" like it is factory. Are you sure that it is a '70? My 2/70 has a full height rib not factory coped for the booster.
