Default how to change diff?

Is there any videos or posts on here about how to change a 94 wrx rear diff? How long does it take? Do they bolt on, or is it complex? thanks
also does the rear diff code have to match the gearbox, if so where do i find this info.

im not familiar with the layout/setup on an impreza, but iv removed a few diffs before. you will need to remove the rear driveshafts, propshaft and then unbolt the diff. Theyre heavier than they look by the way. Make sure you make some marks on propshaft flanges and bolts at both ends, as its important that the prop goes back on the same way it came off. Make sure you fill it with the correct diff oil afterwards.
Im sure someone else will be able to give you a more in depth explanation

With out any issues this is usually under 2 hours work, so around £100.
