The foot pads arrived and they are now installed. Two things I did to help make the installation easier was;
- using a 3/8ths drill bit, I reamed out the holes in the stab jacks so the bolts would slide through easily and
- I slightly bent the tabs on the foot pads so they slid easily over the stab jacks.
Here's a link to the Amazon product page. Seems one could find them cheaper but those cheapies always came with an exorbitant shipping bill.
