You can submit a FOIA request to the Army Material Command and request the drawings (good luck with that). You are going to need the drawing number of the part you are looking for. This can be found in the -20 or -34 TM. Having tried this in the past I can pretty much tell you what their reply will be: 'You want what? HA HA HA HA!" Actual they say something to the effect "The information you have requested is exempt for the FOIA.". But I will post the address where you can send the request. By the way if they do come through with the drawing I expect you to send me a copy.
