Hello, I have a 1996 Ford Mustang GT with a bad motor, I have a 2006 crown vic motor that came with the mustang when I bought it, the previous owner keeps saying they have the exact same block, but I really want to be sure before I try to take out the old engine and try to fit this one in. Also, the crown Vic had an automatic transmission, but my mustang has a manual, will they go together?
