Purchased these hinges fora 1964 chevy truck. Hinges will not hold up the stock steel hood. Hinges were purchased a couple years ago but not installed until now. Product never worked right out of the box. Have contacted Eddie motorsports and they do not want to stand behind their product at all. After spending a premium price on this product I would expect a premium product. Even if the hinges had been installed for a couple years I would expect them to still function, especially considering the original ones functioned for 50 years. I would not recommend this product.
