Hi Everyone, I installed the BT Stiffening Plate tonight. First off, it was a lot easier than installing the XM Radio and success was accomplished in about 15 minutes. Installation was a breeze. I was able to remove the existing plate without raising the car off the ground. Reached under the car on one side taking 2 bolts out and went around to the other side to finish the removal of the remaining two bolts. The new plate was installed by setting the new plate on a cardboard box that was a little lower than the car. The cardboard box made it so I did not need someone elses help holding the plate while putting in the first two bolts. It sounds much more complicated when typing, but in reality the whole process took less than 15 minutes to complete. I tighted the new bolts with the rented torgue wrench ($8 for 4 hours) as suggested by BT. Thanks BT, after taking an evening drive I love the new plate and I wanted to share my experience with everyone. Waiting for the weather to get warming to install new speakers & sub-woofer.
