I first noticed the difference in hose clamps after I bought my 90 ZR-1 used in mid 91. Going to Corvette shows I noticed that the early 90's had the screw clamps and the later ones had the spring clamps. These were all on low mileage cars that were supposedly just like they came from the dealer. I am the third owner of my car and I bought it with around 2100 miles and it was supposedly just like it left the factory. It sure looked like new, the front spoiler hadn't been scraped on anything and the car had never seen rain. A couple of collectors had owned it and they both decided they would rather have something else. Noticeing the different clamps made me wonder how the NCRS people will handle these cars when they get older and they want the car to be just like it was when it left the factory to get the most points. I wonder if they will be able to document when the factory changed from one type clamp to the other. When the original hoses are replaced I imagine most people would switch over to the screw clamps.
