If you do a 153" then you will need 7T 3.0 pitch drivers. Then 2.25-2.5 is lug height you will run. Get a 141" Arctic Cat M-Series suspension. The front holes line up and then you just need fab rear brackets. Less weight and better approach angle with the M-Series vs. the stock Yamaha suspension. Get a tunnel extension from Hartman or MPI. I have done a few of these.
Your nytro skid will not bolt right in without adjustments. You will have to get measurements from your sled and use them on his RX-1. I think there are a few that have done this. Let me know if you have any questions.
