Ya the late model ones are Flat band clamps. They have been used for years and I would imagine most of them are made with recycled materials from China. Lots of clamps on a car and if the manufacturers save a penny on each they save millions $$ every year. Just replace them with a Ideal brand worm style clamp and move on. You need to watch the worm clamps nowdays too. Most are **** as well. That's why I recommended Ideal brand. They are probably the best made. Ideal Tridon - Ideal Tridon
