Star Wars Vehicles

I have the model of the Star Wars Imperial Lamda class shuttle craft but
I
cannot find the stats in the sourcebooks.  Does anyone have it?  I want
to
convert it for use in the Star Wars Miniatures Game as an assauly
shuttle.
 In the Empire Strikes Back Darth Vader rides down in one after being
told by
General Vier that its safe to make his descent.
