I had a similar problem on my orange car. I removed the rubber "plug" from the passenger side of the trunk lid to see if that would help. It did....but too much. I then cut about a third of it off and put it back on....PERFECT.
Mine is lower on the right side than the left, lets face it, the "fit" part of fit and finish were not exactly a strong point with american cars before robotics. I ownmdeer if removing the tension sping and putting in a pitstonm set up like newer cars would work?
Managed to get the heater core replaced tonight, in 90 minutes. All I had to remove was the kick panel & cardboard glovebox liner. Zip it in & out. I took it on a test drive for an hour. Came back dry. Time to put the glovebox liner back in....
My car does same thing on right side, its from tension, of the spring, being put on trunk lid for 35 years! its sucks i know
maybe thats why they closed the Atlanta plant, there putting cars together with rubber mallets haahaa
All three of my mavericks had that problem. I tried adjusting the trunk and took off that bar that makes the trunk pop up. I still could not adjust it and had a real hard time getting that bar back on.
