Not a real z28. No rust issues - very clean underside. Hotchkis front and rear lowering springs. 3.73 POSI. Lots of new parts - wheels/tires, complete brake system, fuel system, Denny's drive shaft, radiator, electric fans. Interior is in great shape- does have crack in dash. Paint has some clear coat peeling and minor flaws. Everything works. Did have a LS1/4L60e which is why the LS stickers are still on it. Car was blown apart and rebuilt - that's why so many new parts. Like any new build, it needs driven more and tweaked.
