My buddie and I put a m8 seat and tank on a 04 kingcat 2 years ago. It worked out good because he had a aftermarket hood on it so we were able to cut it to look good. The other thing I was thinking was putting a 500 sno pro type seat and tank on one. I have my seat and tank off my sno pro in the shop and it looks like it might work better then the m8 stuff.
