Call General Motors Communication center in Oshawa Ontario,@1-800 263-3777 and ask for the Historical data department.The fellow who does all the research on Canadian built cars,and American built cars that sold in Canada brand new is George Zapora.you give him the Vin number and your Visa number and if your car was built here ,in about four weeks after you talk to him you are one happy guy when the post man delivers a big envelope to you.It is amazing the stuff they have kept on old micro feesh on our cars.The last time I had one done it cost about $45 Canadian,so about $30 US.If the 1-800 number does not work in the States then ask the long Distant Operator to give you General motors of Canada Limited on 1908 Colonel Sam Drive,Oshawa Ontario's phone Number.
Too bad the US didn't see fit to keep track of all the Chevelle related info...they could be making a fortune sending out the info to collectors and restorers......The last year they counted Super Sport Elkys was in 1978....12,027 of them [the "just stripes and wheels" models, yes, but they did have the same motor as the Z/28 (LM-1...170 hp) available].
