You can also use these parts numbers- LH-3902519 RH-3902520. I had a set that I sold about a year and a half ago after I swapped in the ride tech tru-turn setup. I bought them several years ago for a similar suspension setup, they were really hard to find. Good luck in your search. Here is a link to my old for sale ad that has some pics of them for reference.
