Hello, Having trouble finding a part breakdown web site. I resently had some work done at the top of my mast(stuck cable) Is there suppose to be some kind of a weather head or cap on this mast. It looks like the sheaves are in the weather now after work was done. Does some one know if there is suppose to be a cover over the mast head and direct me to a picture of what it looked like from the factory/ Thanks in advance Norm
