Nice looking Chevelle. I worked for a gentleman who had a large collection of cars. I have been left with the task of selling some of them. One of the cars is a 1969 Chevelle 2dr post. A long time ago I asked my boss if he had the original engine and he said yes. Right now the first thing I am doing is to verify if it is truly an SS car. I have gone through his collection of BBC engines (6 of them) and cannot find one with the partial vin on it. When my boss would paint a car he removed the cowl data plate but had a bad habit of not putting them back on. I found one stack of data plates but the Chevelle one wasn't there. What can I check to verify that this is or is not an SS car? It has the 12 bolt rear end with the back half of the lower control arms boxed in. It also has a single fuel line. Thanks in advance for any suggestions or input.
