Has anyone changed hinges on the deck lid with out breaking the rear glass?

All the time. I just removed the springs from some hinges since I put gas springs on.

Get a strap clamp with hooks. Hook on the bottom loop where the pin is in the hinge. Hook the other end to the trunk lip and pull the bottom end of the spring rearward until you can remove the pin. Then release the spring.
Repeat on the other side. Once you have that done you can pop the springs out of the fingers under the rear window and you home free to remove the hinges.

Dodgerunner has it right but I choose to anchor the hold down straps to a large tree with a tow strap. I then ratchet the torsion spring away from the holding pin and pull the holding pin out. Then I release the strap ratchet and relax the torsion springs . At this point they can be removed safely by hand. If you use this method there is little to no chance of breaking the rear window.

Yeah I learned how much tension those things have on them one day at the junkyard. I unbolted the hinges and had my had on the top of the hinge, it didn't break out the window but I sure wont do it that way again. After I had them loose I noticed the pins. Haha.

1986 GT. I removed the decklid wing, but now the torsion rod tension is too much. If I pop the decklid switch I've got to have my other hand at the rear of the roof to catch the lid ... it flies up too fast. I have the service manual and have read this thread, but wanted to know if anyone has an alternative process for removing the torque rod retaining pin. The torque rod sits over the top of the pin and needs to be moved rearward before the pin can be removed. Not looking forward to finding a come a long and backing up to a tree to move the torque rod. Doesn't seem to be enough room to get a pry bar back there so maybe that's what I'll need to do. The service manual just states to move the pin forward or backward to increase/decrease tension. Says nothing about how to move the torque rod. Any thoughts?

Rachet tie down to pull it back, move pin, relief pressure....

Thanks olejoedad,
I think that I'll head over to Lowe's and buy a ratcheting tie down. I've got a bunch of trees in my yard so I'll just back the car up to one and use my standing lumber as an anchor for the tie down.
