On Ebay there is a polaris 400 sport and he said he might trade for my 2000 blaster. It has a pipe/sil., tires, etc. my blaster has a filter and reeds. I was thinking about trading. I have two ?'s: Is it worth trading, 2. Can you put a 4wd shaft out of a scrambler onto the sport for 4wd. thanx abunch ttyl cya
