We have a 2007 21 EC, can you tell me or send me a picture of what the baseplate for the mast looks like. We have to replace ours and Tim, at Wefings, thinks that it is a new style now compared to what was used in 2007. I could also use some advice on replacing this, will I have to remove the headliner inside the cab? The boat is in Florida, with my father, for the winter and I am still here in Indiana gathering tools.
