Engine stands typically use the bell housing mounting bolts to secure the engine or the trans to the stand. Unless you are thinking of a different type of stand than the typical you may have a hard time finding what you seek. If you are looking for a regular style stand you can work on either and engine or a trans, not at the same time, you can get one at most auto parts stores for about 30 dollar. Be sure to get one with four wheels and STAY AWAY from the one with only three wheels. They are unstable.
