I have an 89 SC with a blown sub-woofer. I'm taking out the sub box from the trunk to replace the speaker. The problem is with the 2 bolts that hold the box towards the front of the car (under the rear shelf). The bolts just turn when I try to remove the nuts. I don't know how to access the top of the bolts to grip them while I remove the nuts. Do I need to remove the rear parcel shelf? If so, how do I do it. Any advice would be VERY appreciated.
