Well, make this sticky because it will save many people the $450 plus 2 hours of labor to attempt the install.
What I have on my wrx is:
JDM 6spd
JDM r180 rear diff
What I was using for a propeller shaft:
1995 Automatic Impreza shaft
What I tried to fit:
USDM Sti 2004 propeller shaft
The end result:
It is 1:30 am and I am furious
Close to lining up
Opps, not really
Argggg
I recall a few people stating it would fit, I guess until you personally try do not rely on 2nd hand infoI'm just pissed from spending 2 hours on my back for nothing.

The flange for the R-160 and R180 can be swapped, easy! Just go to junk yard and get the right flange and pull off the old, put on the right size. The input shaft and splines are the same in both diffs. No need to get a different driveshaft!
You can get the flange off of any Japanese car with a R180, it is a Nissan diff.
I have a US R180 on my WRX, it has the larger flange, I can use my stock driveshaft with my flange from my old R160, or I can put on the larger flange and use my one piece aluminum shaft from the driveshaft shop. Sorry you guys had to spend $$, and drill holes. That is not the right way!Now the output shafts going to axels are different, so you will need the US,STi axels, hubs, bearings, and carrier (upright) (spindle). Bottom line, yes, any driveshaft will work with both diffs.

I use a five speed dogbox, so the length of shaft is the same, if anyone is wondering, the R180 and the R160 have the flange in the same spot. To take off the diff input flange, just take off the nut, and pull it off!The stock WRX driveshaft has lasted me a long time, but I did have a problem on the tranny side. The splined end twisted on the output shaft of tranny, so I got some spicer U-joints and better metal on the splines of shaft with my one piece aluminum one. I have never been to a dyno, but have been in the 10s @130mph. So I guess that may be the limit of the stocker. The STi seems to have the same shaft (except for legnth), and for the flange going to rear diff is bigger. The stock WRX shaft can be cut, and a better U-joint welded on, along with better material for splined area. This is an option, or just order an STI driveshaft, but it is not much different, just shorter.

this should be un-stuck. there is no real problem. All diffs can work with all shafts!

Ok so, the WRX R160 and JDM R180 are the same flange, and USDM R180 has the bigger flange, right? I just wanna make sure I am understanding this right.
The flange can be taken off any subaru rear diff, and be used on any other rear diff. There are hundreds of flanges in the juck yard. Yes the USDM flange for the Sti (R180) has a larger bolt pattern, but a WRX flange will fit fine. I have no clue what a JDM Sti has.
Can you diagram this compatibility in some kind of chart?
I have an 06 WRX and I'm going to be swapping in an 06 STi tranny with R180 and the STi driveshaft. I know that is straight forward but are you saying I can use the factory 06 WRX driveshaft and just swap the flanges on the R180 and R160?
No the two trannys are different legnths and you will be needing the shorter DS from the STi. You could just keep your R160 and get a flange from an R180 diff.
Another example is I have a short, five speed Dogbox(again, six-speed is longer) with an R180 rear. I can't use an STi DS...it's too short! I had to use a regular WRX DS and swapped my flange on the STi diff to mate with a regular (smaller) flange from the wrx. But Now I have a custom one piece DS with the larger flange....so I put back on the Larger flange on my R180..
Wanna buy an MRT Dogbox?? $4000 and it's yours. I have three different 4th gear ratios. It's a straight cut screamer. Cost me around $10,000 and will handle more HP than a STi tranny. Chit, but my whole car and toys! Hydra ECU, a few engines, spares, New (never started!)EJ22 with Crower pro-rods, titanium retainers and upgraded springs for BIG BOOST. AVO 500 turbo, etc....

Ok so you're saying I can use the STi Trans and STi Driveshaft with my R160 rear diff as long as I pull the flange off of my R160 and pull the flange off the R180 that I received and install the R180 flange onto the R160?
Do you have a picture of the process or of the two flanges? This makes things sound a WHOLE lot easier!
