Junkyard finds?

So I have a huge junkyard nearby in my city, want to go to look around, not expecting to find anything, but here is my goal. Assuming I do not find a 3s, I am trying to learn where the transmission for the 3S, a 6 speed getrag, could be found, IF it can be found. I am not worried about disassembly, or condition, all I hope to learn is what other platforms this transmission can be found in. Google, wiki, ebay, other 3s sites, haven't found much luck learning but if anyone on this site has any information on other platforms using 6 speed trans that are compatible, I want to learn please! Thanks.

The W6MG1 is not in any other vehicle besides a 2G 3S. It pretty much doesn't have any known parts commonality with other transmissions with the exception of the 2nd gear synchro parts which are used in the 1997 Porsche 911 Turbo (any 911 equipped with the G50), and some of the Supra V160 synchro parts work but they are slightly different.

Thanks for clearing it up. No wonder I have so much trouble finding out info about this question. I was beginning to believe what you said, that it is individual to the 2G 3S. Thanks for clearing it up in easy words for me!
