The IDF did use the WC51. It would have been most used in the 1956 War and the Six Day War. By the early 70s the Israelis were producing their own weapons carrier, the M325 "Nun-Nun", so the WC51 may not have been as common during the Yom Kippur War. As for its specific employment (beyond commenting on what I've seen in photos), I can't provide you any more info other than these two which were used as a base for a flagpole and a stage on which a certain one-eyed soldier could stand in Sherem el Sheikh, 5 November 1956.
