I installed a power beyond kit on my 4320 open station tractor. I think the install would be the same for a cab machine since all of the work is done at the back of the machine and the side of the transaxle case. The kit was purchased from the dealer and included all the instructions needed for installation. The kit was not cheap as is the case with all Deere parts, but everything fit without me having to curse the engineer or parts picker who made up the kit. If your handy with tools and are not in a rush it's a fairly easy job. Go for it!
