Lakewood Muscle Motor Mounts, while not urethane, are built such that the steel overlaps without touching. This design negates the need for torque straps or chains.
The TCP mounts are a bit pricey (understatement), but the design of them is similar to the Lakewood stuff, only a bit more extreme. The rubber mount is completely contained in the steel. There is no way to break it. Period.
Here is the Lakewood catalog in PDF format:

Summit carries the Lakewood mounts, but does not list the Ford parts. You will have to call them.
Jegs also carries the Lakewood mounts, but will take a phone call to order the Ford parts.
It looks like
RaceSearch.com carries the entire Lakewood product line. Racesearch is typically cheaper than either Summit or Jegs too.
Darkhorse Performance also carries the Lakewood line.
