WOW Mullet man, nice job, I'm sure this is why most havn't had anything to say lol, you have seemed to cover all the bases, and it looks FANTASIC!
How did you find the ride? any bumpsteer? are you using the stock banshee wheels or are you inverting them?
Now that we know you can make the 450 arms fit, a complete clip would be awsome, utilizing the better brakes and shocks as well, and I belive the spindles are aluminum like the raptor.
You have also done a fantastic job on the "how to" layout, I used to write up SOP's (standard operating procedures) when I was a millwrite and I always seemed to forget something lol.
If my opinion matters, I say you've done an awsome job, I'm gonna go hunt down some 450 arms now before they turn into gold on ebay LOL!
