I own a 1979 elcamino SS factory 4 speed I have been working on it since retirement 5 years ago, slow progress. I see a lot of Questions about how to tell a real SS ,well 1978,79,80 have a elcamino ss badge on right side of the dash board to the left of the glovebox if missing there will be two small staggered holes ' These emblems are not available like 1981 and up.Thats my 2 cents all have a good evening.
