Just about all the parts that were missing on my engine (pulleys, brackets, etc...) have now been replaced with repop. I'm sorry, but I refuse to pay STUPID prices on an original pulley, when a $50 reproduction will work just fine. Sure, I may have to "adjust" it a bit, but once it's on, no one's the wiser.
There are lots of people in the world that demand this kind of money for original smog setups, engine blocks, rear axles, or whatever, which is why my car will NEVER be "restored". Being one of the 99 percent, I just can't afford them. But unfortunately, there will always be people out there with loads more money than brains, so these parts will sell, but really, at what price? I know I'd not want to have this kind of reputation.
