I'm a pro at taking the radiator out of a 1965 Riviera. After wanting to keep the old radiator. It had been recored before I bought the car. I had it out probably 7 times. Over heating issues, and leaks. I spent over $300 to keep the original radiator. To end the drama I bought a new one from US Radiator. NO issues in 3 years. If I had it to do over. I would have done it much quicker. And got an aluminum radiator. And saved $$$$. It's so hard to find a good radiator shop. Good Luck, Bill
