I've just pulled my copy of Carter's "DFC, and how it was won..." off the shelf, and unfortunately it doesn't contain a citation for Hibbert's DFC, merely a LG date of 27-3-45.
A search of the LG online archives produces the following page, but again, no citation: -

It is my intention to get the 156 Sqn ORB, as a lot of 1 Group men went to that Sqn as Pathfinders, but alas, it is still on my "to do" list i'm afraid. Sorry i can't help any more than that.
