The tail cover will come off with a chisel and a hammer. Do don't even need to whack it too hard, just soft taps around the bottom side of it should split it fairly easily. I wouldn't recommend drill bits. You really need something with straight taper edge.

LOL, the drill bits are for getting that roll pin out ;-)

Just found a write up at another site:

Ok, I literally have one thing keeping me from getting the center diff off - the roll pin in shifter linkage.

I had exactly the same problem trying to get the tail cover off an Impreza at the breakers yard, going back with a bag of old drill bits and a hammer - hopefully no-one else beat me too it.

Regarding the use of a 'cooler' plug, is this affected by altitude?

I'm running at around 3400ft above sea level, would the thinner air (around 90% of O2 compaired to sea level) affect the combustion or would it be negileable with the turbo boost?
