Anybody know why the 65 convertible top fuse is different than the 66. The 66 is made totally different. THEN it appears Ford went back to the originial design. The reason I ask is, I have to install one and I was wondering if there was a major shortcoming/design flaw with the 66 version that would be correct for my car. I don't know if it makes a difference which one I put on there to be honest as long as it meets the electrical requirements.
