TF 727 Guru?

Every 727 I do has been apart before. I never rely on case numbers because they won't tell me what's been changed. When people call me up and start spouting case numbers, I know they aren't mechanics. They try to tell me they have a virgin transmission...you know what I think next right? If you think you can run numbers and get the right parts for a trans, you're just setting yourself up for a lot of shipping charges back and forth. Not only does the output shaft have to match the front planetary and the back of the input shaft, but the input shaft/forward drum has to match the pump; same as the direct drum bushing width has to match the pump. I always get the front planetary with the output shaft so I don't waste time running around. After, of course, I match the front of the output shaft with the back of the input shaft. Or you could just flip a coin..

Don't get yer knickers in a wad. I Never said I was a mechanic. In fact I said I don't know much about transmissions. It would seem to me though that the average seller of a tail housing and shaft would not ordinarily also have the front planetary to go with it. So, assuming this, how am I supposed to obtain the correct one? If this is all true then I suppose I should just toss my trans in the trash and buy a whole new unit. Right? I came here for help, not to be ridiculed and confused. I don't have a ton of cash to through around, I just want to get the right thing to put this trans in my car.
