I forgot to suggest as well to the people using a doubled up shock tower. IF you car about the shock angle and body mount position you can do the following. Glue the extra shock tower on the back front side ( the side closer to the front of the car). Cut off the bottom where it mounts to the bulkhead and cut off the edges where the body mounts go. This will keep everything in the original position. If you just glue two together, you can put some spacers on the lower shock mount position to ge the angle straight.
