Does the trunk on your Fox Body Mustang Coupe feel floppy? More than likely the tension rods (bars) have disengaged themselves from the trunk arms.
This common problem is an easy fix with the help of this easy-to-follow how-to tech article and a little muscle power! If you have a 1979-93 Fox Body Mustang Coupe, it's possible that at some point, you may have had one of the tension bars/rods that hold the trunk up pop out of the hinge. We had a customer ask us how these tension bars should look while in the proper location, so we thought we'd take a few pictures showing the proper position. Luckily, we had two Fox Body coupe Mustangs in our parking lot. One had the rod in place; the other didn't. Follow along as we show you how to re-install your trunk tension rods!
This is what it looks like when the tension bars are out of place.
Before you try and twist the rod back into position, you will need to make sure that the other side of the hinge isn't set in one of the three different notches (pictured below) because this determines the tension of the rod, which can make twisting the other side into position much more difficult.
When you are getting ready to put the tension rod back into position you will need to twist them counterclockwise toward the rear of the Stang.
Once you have them twisted enough, you will need to put the rod into this hole in the hinge.
This is what it looks like once the rod is placed into the hole.
The last step is to set the tension on the three different notches mentioned earlier. Once you set the tension, you're all done!
