I'm attempting to put my hardtop on for some cold weather driving for the first time in three years. While attempting to put top on I noticed both top chrome locknuts in center are misssing. Is there a way to lock top down without the chrome nuts? Any ticks I need to know (like socket..etc) I want to get top locked down so I can drive ASAP. Other car is having engine overhauled, I also would like to know where can these be found, purchased so I can fixed this problem for good. Thanks................
