Please understand that a majority of these posters are not that mechanically inclined. Let alone anyone doing an engine swap. To address your question, having done many engine swaps and motor mount fabrications over the years, look at another MB and come as close to that set up as possible. Dont try to re engineer the set up. Engine mounts on an engine are very critical to cancelling out vibration as you know. Go with what they engineered. I guess I've now set myself up for somebodys rant! Oh well!
