You need a big shoehorn and a reciprocating saw. It should take about 10 minutes. Seriously, it's not all that hard and there are a lot of different ways to do it. Just surf around a little and you should find numerous write ups on it. It has become so common that there are used swap parts out there as well. Best of luck should you go for it and we would like to see the buildup in progress...:thumbsup:
