If you want to lower the rear deck lid, to get it tighter against the weather striping, you have to put a shim between the deck lid and the hinge, on the rear bolt. To raise the lid you put shims on the front bolt.

Also is the problem in the rear of the deck lid or at the front. If the front is up then you need to adjust the latch catch down on the car to lower the front of the deck lid.
