22k for something that probably cost about a grand new!!! Yeah, this set-up is incredibly rare and much sought after, but what does it do to the value of an original Z28? They were sold over the counter, so documentation on any particular car is both unavailable and irrelevent. Can you just slap this on your DZ302 and call it "authentic", really? If the market price on an original '69 Z is "X", would the car actually be worth "X" + 22K when it's installed on it, or is the setup worth more uninstalled? Food for thought...
