So, let's say I can get this '73 for next to nothing. What is the process to convert something like my '90 to a full convertible? We do have shop access, for torch and welder, but not a whole lot of experience. I'm taking a break from putting one of those antennas that is part of the windshield in. My new windshield has the antenna and our parts truck (just a barren cab now) had the wire. It was much easier taking out the old one, with no dash or ducts. Ducts are a PITA!
