These older P/S car werent so far removed from factory stuff--that's exactly why may of us love 'em so much. The later tube chassised cars (2nd gen. is what I call 'em) may have been faster, but hardly "stock" anything so They can kinda be disappointing to those that remember what the class was originally designed for.
Truth be told, a case could be made for a stock K-memeber/coil-over front-end may be considered a "safety modification" & therefore a valid mod from "stock". Back then there just wasn't that much difference from production vehicles.....
