Hi Captain Jack. My name is Michael and I currently own a 1970 Cal 27 with the Pop Top. I gotta tell you. I absolutely love that pop top! I'm currently working on engineering a lift support system to assist in getting that thing up and down. LOL I have posted some pictures of 'Starship Del Rocio' on my page. I have a TON of documentation. Please let me know what I can help with.
