Is it possible to use 450r a arms on a 400ex. I have an 07 400 and I want to go wider on the front. I already had to replace the axle so i went to a plus 1. Anyhow Im hoping to just swap with a 450 rather than going after market. Trying to save money and upgrade engine instead. If someone knows help me out. I know that the 400 arms are 8inches at center where they meet the frame> Thanks again/
