Where do I hook up a tow rope on rear of fiero gt 1987 I just need to pull it back about 6 or 7 ft.

SOURCE: WHERE TO SAFELY HOOK A TOW ROPE

you can hook unto the bottom side of the frame directly below the engine. This is the strongest part of the frame, don't hook to the sway bar or steering linkage. There are a number of large holes in the frame where you can hook a chain. Be sure to wrap it around the frame and then hook it so it doesn't come unhooked by accident.
