I don't know where you are located in the world, but I'd be more than willing to take you around Messier-Dowty's test engineering centre in Gloucester, UK where we are currently testing Airbus and military aircraft landing gears for noise and vibration reduction.
I work for Messier-Dowty who manufacture landing gear for Airbus aircraft. Our competitors, Goodrich, are the suppliers of gears for Boeing aircraft. If they are as strict with respect to drawings & dimensions as us you wont get through the door!
