Impreza Axle back fit Legacy?

So been offered a swap for a Blitz NUR 05 Impreza Axle back which is exactly what I'm after but not sure if will fit?
I've been looking at images and comparing them.and they look fairly similar but looking to know for sure will it fit?
My legacy is a salloon so length wise should be the same as the Impreza I'm just wondering will it bolt straight up?
Any info would be great!

what year leggy is it for?

99 b4 be5

No it'll be longer

No.
