No need for the special tools. On a LH drive car, the driver's side intake cam (upper one) will probably move out of position due to spring pressure when the old TB is removed. Be prepared for this with a wrench on the cam sprocket bolt and ease the cam down CCW to where the spring pressure eases off. Then, when installing the new TB, use a wrench turn the sprocket CW back to where it was so the timing marks line up. Hold it there while you wrap the belt around the sprocket and then a couple more sprockets/pulleys and you can release the wrench.
