You will probably need to swap the rear diff flange for the propshaft, and re-use your legacy one. The nut will be very tight, and use a puller to remove the flange, and push it back on gently, and re-tighten. Dont hammer the flange back on.
You may also need new rear driveshafts, as I the Plate type LSD uses different driveshafts from the normal VC unit. Impreza shafts will fit a legacy, altho the propshaft is different.

Just thinking, any UK legacy rear shafts are different from impreza. The Uk legacy shafts fit in using the same was as the front diff, where a roll pin is used to retain them to a stub sticking out from the diff.
Impreza shafts slide into the diff unit.
Then there are the impreza rear shafts for a VC diff, and different ones for a Plate type LSD
Jap legacy RS shafts seem to be the same as impreza ones.
Since you got all the bits anyway, just a little bit of useles info.
Dont forget to be gentle removing/replacing the rear diff drive flange.
