After the recent fire of my business I have decided to invest in some some of my favorite cars I am looking at a 69 SS427 the owner claims it is a 425 hp car The options i have found on the car are Hideaway lighting ?? A concern thought that was Caprice only. fully loaded interior, buckets 4sp posi, tilt, air, power windows, gauge package no tach,() trunk emblem is the same as 68 ?? this is a 99% rust free car with a lot of nos trim less motor and trans. My next trip to look at the car will determine if it is authentic hopefully with some help from this site What should i be looking for. Any help would be great.
