Oh, yea, I forgot to mention that the decals are stickers, so you don't have to include them. The holes are normal pin-holes and you can fit a pin, axle, hose or whatever in there. I will measure everythingthing tomorrow 
Btw, if you want to make a really detailed version of the part, you have to include 2 engraved LEGO logos on the back... But that's not necesary for the part usage, so the choice is your.
