As Dave said any mount that mounts the engine and then goes clear out to the original stock pads will flex and the engine will bouce. While a good idea it proved to be problematic as the engine is heavier and the tube was not as stiff as the forged original 4 mount. Patrick now makes a bulkhead mount that uses a mount similar to the stock piece that mounts to the engine and a short tude section with dual feet that attach to the bulkhead where there are two raised metal sections. This uses bushings to capture some vibration and a big advantage is the engine and trans can be lowered at the rear which makes trans swaps super easy. Quite a few vintage 2L class race cars (912s and 914s) that have been converted to sixes use them.
