Not much has happened lately. In another post, I saw a link to a company that made polyurethane motor mounts. I contacted the company, and they noted that they hadn't made those mounts for years. The contact did offer up another company that made such parts for turbo T-birds/Cougars/SVOs. I contacted them, and they said they had one set for the SVO in inventory, but were about to make another run and build more. I ordered that last set they had today. I'll report on how they look when they arrive. For reference, the company is here:

Their Series 2 mounts are $175 shipped. They also make EGR block off plates.
