Are you looking for the end link bushings or the bar to fame mount bushings?
Moog makes an end link kit that are urethane for that vehicle, it appears from their website.
The bar mounting bushings they show are still the rubber ones.
For the bar mount, using the rubber isn't as large a downside as the links, handling wise, but they will not last as long.
Best to go to Energy Suspension and match up the bar diameter and as many other dimensions as you can and count on having to probably modify the mounting a bit.
All urethane bushings are going to need periodic greasing to prevent squeaking.
