Is that the one at Mike's?  If it is, it's good to see it going to be used
instead of being made into toasters, etc.  although I notice that the scrap
price is going down - the crushing rate has slowed down a bit.
In order to operate the climate coltrol, you'll have to get a special vacuum
pump, it looks very similar to the Cruise control pump but functions a bit
differently, I guess the TD does not scavenge (and save) vacuum from the
intake manifold like the gas turbo systems do.
You might also need things like a fuel pump (apparently those diesel units
really crank out some serious pressure) and other trinkets.  The family
album may be of some service in listing parts for the diesel engine.
