title says it all..

 

I am pretty sure that trail boss plastic will not fit a trailblazer. Now the sport and trailblazer and the scrambler, they all will fit each other.

 

Depends on how much work you're willing to put in it, and how the finished results may look. The seat would have to be changed also. If you have changed the exhaust, I'm pretty sure it will melt the plastic. The only advantage from changing the Blazer plastic to the Boss, would be it keeping more of the mud off of you. Mud guards would be cheaper and easier. Personally, I'd like to put the Blazer/Scrambler plastic on my Boss.

 

I have seen quads go from the boss plastic to the trailblazer plastic so I would assume that you could trade the blazer plastic out for boss plastic too. You will have to change the seat and seat pan out too.
