I finally got my rear spoiler assembly on ,I had many repairs to the original fiberglass piece ,and a couple of repairs to the rubber lip section . The assembly is fully removable , I made 4 new metal brackets and epoxyed them to the underside of the spoiler and drilled and tapped holes in each on either end i had a stud coming down through the lid , the studs were 4mm and the mounting nuts are visible on the underside of the lid , the axcess holes for the screws going into my brackets are hidden .Unfortunatly I put a chip in the top of the right quarter panel in the fitting process , Two steps foward one step back.
