I just bought a 1989 4x4 toyota pickup x-cab with the 3ZVE V6 engine. At 185k miles, the engine still runs great but the body need some help since there's a big hole in the driver side rocker panel. Is there any places where they sell replacement sheet metal body parts such as the rocker panels? Also, does the 3VZE have any weakness to look at? I heard about head gasket leaks!? Thanks!
