Could someone with an original Star War Yoke help me out and give me the "Main-body" external measurements ?
Thanks in advance 
Are you looking for a
mounting template or maybe a Solidworks
3D model or the simple measurements below?
The mounting plate is 4 1/4" square.
The housing that holds the handles is 5" deep, 4 1/2" square at the base, tapering to 4 1/2"w x 3 1/4"h. (excludes handles)
There is 0.15" clearance between the mounting plate and the housing.
