Delrin bushings for UCAs and LCAs?

Anybody here use Delrin bushings for LCAs or UCAs ? If so, with what UCA/LCA ?

Delrin is a much stiffer and more durable material, and is used in bushings on on other vehicles, and I was just curious if anybody had tried it with success on the Tacoma.

 

I'm using them on a total chaos long travel. They have lasted 40,000 miles so far. In that time I have replaced the uniballs twice just to give you an idea of how hard I am on them.

They are not easy to install. I put them in the freezer overnight and still had to press them in.
