the banshee swing arm is completely different. On the banshee swingarm the shock bolts up to a dogbone that is below the swingarm. The blaster does not have this dogbone and the shock mounts on the top of the swingarm. The blaster swing arm mounts to the rear of the engine, on the banshee the swingarm mounts to the frame behond the engine.
Brakes, the rear brake mounts on the banshee and blaster seem to look the same but I believe the banshee one is larger and sits up higher. It may be possible but I dont know.
I will try and get a pic up later to show what I mean.
