I think the 13" diameter steering wheel on my 09 Teryx is too small. I'd like a 15" wheel but research into the change over is confusing. Grant Wheels first told me I need Adapter Kit 470-4673...then the same Grant employee said, "no, you want Kit 470-3677 because the 4673 only fits the Mule". I found a thread by Puddle Jumper from April 08 and he used the 4673 Kit. Since either Kit has to be special ordered, can anyone clarify this so I can get the right darn adapter. Also, do you have any opinions on whether the bigger wheel is a smart move?
