Alan,
I have the tool referenced above. You take the cup out of the floor jack, and the tool has a pin that fits snuggly into the jack. Here are two better pictures.
The upside down picture you can clearly see the pin at the top of the picture that fits into the floor jack. The right side up picture, the right side is what goes under the sump cover, and the left part goes around the large boss on the rear of the case. If you want some more pictures of it attached to my jack, I can take some this weekend.
