Hello I just purchased a 1973 oday 23 pop top. The Hull itself is not in bad shape but there is a few parts missing that are very important. Since its a pop top the cabin roof will slide up and down the keel step mast well I dont think I have all the parts in the cabin for the mast to step on and another thing I dont know where the mechanism for raising the cabin roof up is located any info would be helpful I can not find a owners manual anywhere online or the parts I need. Thank you
