going to make the trek to look at a 70 RS/z28 today. not original motor, trans and now see it has a 10 bolt. has correct speedo, tach, torsion bars, tail lights. to seller's knowledge it is a z28. what do you guys think? any feedback appreciated supposed to leave in a few hours to go look it over. don't want to waste my time if real chance its not true z28.
