Question for you guys that have the Ultrex 52" shaft... I've been told the cover will not fit on it after swapping your Fortrex 45" shaft out on Z520C. Are you having the same experience? My cover is tight as it is with my 45" Fortrex. Thoughts? Can you send it back to Ranger for them to replace the cover patch in that area to make it larger? I suspect not. Thanks.
