I have a 2007 Tahoe 216WT. The rear swim ladder handle as lost a nut and is very loose. Does anyone have any idea how to put on a nut and tighten the other ones down there. The nuts are on the inside. I could send a small child down there but then they would not know why I sent them down there. My point is that there is not enough room to get in there. Is there a special looooong wrench??? any advice or help would be appreciated.
