727 Lock up converter choices?

OK... HERE is my SECRET PASSWORD... NOW, CAN I GET SOME ASSISTANCE??
PK4058384 8720 7883. I still do not know WHY this has been made so difficult... I just wanted some info. is that somehow too damn much to ask, around here? It usually hasn't been for me here, to this point. I thought that was the whole reason behind the existence of this website. Info about subjects related to older Chrysler products. Right?
seems like if anyone else asked for info about torque converters available for a lockup 727, and what stall was available, (factory or aftermarket) along with difference in stall RPM between a factory low stall and high stall rated TC they would have gotten a reasonable answer, with much less hassle? Or having to PROVE to anyone else that that was actually what they HAD?
I dont understand the grandstanding and refusal to answer what I asked..... if NOBODY on the forum truly knows, (which I find hard to believe) that would be different.

and BTW I had an 81 W150 with a 318/ and it, too, had a lockup converter..... as did the 1980 4wd 727, that my son got, to put into his 89 Ramcharger... yet the original 727 that was replaced from the Ramcharger, did not. so its not "hard and fast" that "all 19XX year 727s either did/or didn't come with a lockup, after about '78ish....
I am not a trans expert, but give me some credit for knowing something.. I have been around Chrysler products since I can remember, have been inside several of their transmissions over the years, do ALL of my own mechanical work, have never owned anything BUT Chrysler products, in over 35 years of driving and owning vehicles, and work as a fleet mechanic for a living. so cut me some slack here. Or do you possess the ONLY replacement converter, that may suit my needs?

and having done a search on this very site using that PK number, I had hit on someone having had another trans, with this same number on it that they were selling... Imagine that!!!!!! this is not a "one of none" trans!!!
