Ned, I think if we add this picture (attached) at the end, it will add to the other to show nothing is touching the door skin, for less chance of damage. Also, the biggest share of the floor jacks similar to the one shown will have a 1.90 diameter for the "pin", which was the 1-1/2" NPT pipe size. I think it would help out with finding materials to add that part's size. Most of the other items are flexible that someone could use alternate sizes based on what's in the scrap pile.
I'll show this item at the demo this weekend for anyone interested.
