I was JUST feelin good about my efforts and now I gotta think of taking it up a notch. Darn. Well since the panels seem to be in good shape and pulling them was not hard, maybe I will do a test of how they sound now and then an upgrade in the future. I am replacing the foam around the door hadles, cranks, and locking mech, tho.
