Default GC8 -> BD5 Subframe assembly swap

I found a good condition subframe from a GC8 STi thingading for sale at 550 European Roubles. The diff on it should be the locking variety and it comes with all the brakes, control arms and such.
Link below:

a Finnish site so you'll not understand much but what can I do.

Now the question is, can I swap the assemlby as is into my BD5 Legacy?
I have no idea if the bolt holes match up. I'd imagine they do since Subarus are like legos but if anyone has info I'd like to know.

Also need to find out if the diff ratios are the same. Don't wanna bust my transmission or the new diff.

If anyone knows the answers, I'd appreciate it.

That is a GD rear subframe and will not bolt up to your Legacy. No idea about the diff ratio or anything else as there is too little information to identify anything on the linked site.

That is a real bummer. I did find out the diff ratios tho. If google doesn't lie mine is 3.9:1 and on the one in the link it's 4.1:1.
So not compatible without a trans swap.
