Option 1) Power Addiction motor plate, notch PTO bulkhead to clear cases, notch MAG bulkhead if running oil pump, get Power Addiction billet carb boots, mod the airbox and fit pipes.
Option 2) Use Polaris mod BB straps and add a spacer(1.5" or 2" I don't remember exactly right now), modify steering hoop and post or buy the Polaris mod steering hoop and post, notch MAG bulkhead if running oil pump, use filters or make custom airbox and fit pipes.
