Your fitup tools may need to include torch & welder. My M600 had a factory cage and had pads welded for it to bolt to. I have seen 600's with no pads to bolt to and Ive seen a different type of flip forward cage on a 600 that would have required a different type of frame weldment. That said, the M600's 610's 500's have a very similar frame, easiest swap. 610 cages are the most common. -Scott
