Hey y’all, new here. My son and I picked up a 77 Camaro LT. We are trying to gain access to the torsion bars but are stymied. The trunk lid was easy enough to remove but there is a smaller access panel just below the rear window which covers the hinges and torsion bars. There are 3 screws we removed but this panel just won’t come loose. It appears to be secured somehow to the rear window area but we cannot gain access to it. Anyone have any ideas? Thanks for your time!
