It appears to have been a very nice restoration 15 yrs ago (1997 or so) on what appears to have been a very nice original Z28/RS (probably a different color than black!). Seems the trim tag was changed (repro?) to get the black color with houndstooth interior), but the main numbers (engine, trans, etc) seem correct per the protecto-plate? and at that time, Ricks had access to very nice original parts.... shocks? JL8 rear? Cross Ram?.... all those parts are worth big money. The surface rust is what you get when you 'restore' your car and leave metal parts unprotected.. (just as the new cars you buy ... go look at their undersides after 15 yrs!). If I work on a part of my car, I don't like to leave the metal unprotected; if I have to clean it once, I want to protect it better than the factory did, but the builders of that car were going for *points* in a national meet, and they apparently got them! I think that's a nice car with some great parts, Yes, it's a little dirty from some driving and has the age of a 15 yr old restoration, but overall a very nice car. (but i'd rather have the original trim tag, whatever the color, than a fake one - just my opinion!)..
Note: Most car clubs judging standards today allow use of clear or semi-flat black paint on such parts...
