Yup, these throttle bodies bolt onto a Weber side draft manifold.

TWM routinely advertises in various car magazines including Grass
Roots Motorsports, as I recall. They are also available from
Electromotive, who use them in some of their kits.

Yup.

Well don't forget that the throttle body is just the beginning
of a lot of hardware to retro-fit fuel injection to a carburated
car. You'll still need the injectors themselves, an electronic
controller of some sort (I'm leaning toward the Electromotive
unit, obviously), and a higher pressure fuel pump. You'll also
need to re-plumb the fuel lines to handle the higher pressure
and include a return line, and you'll need to modify the gas
tank to take the return from the fuel rail. Its not easy, nor
is it cheap, but it might be a big improvement especially if
the rest of the engine has been modified to take advantage
of the system.
