I followed the Planetisuzoo article and now have 4Hi. this was a very easy mod to do. it only took 2 hours total. now I'm just drooling for the first big snow storm. i did a search and found a few people say they were going to do this but no one posted back to say they did it. am i the only one? well, sorry no pics as my camera has died. I'll try to get some later.
