yes there is a back order on the oil filter housings, what i can offer and ONLY a suggestion from my experience working on them is even on my own 2011 i swapped it out for the newer filter design and from one we had laying around the shop. all i did was replace just the gaskets. It's not a 100% guarantee that it wont happen again, but from doing theses housings i have found that it usually doesnt crack its only just the gaskets.
