Not sure what bell housing I am using or how to identify it either for that matter. I do have a large 1" spacer however, one of the threaded holes is broken so only one large bolt holds the pivot on. I have it solid with locktite and it has not moved while I was using it. I realize it is not ideal but it would require replacing the bellhousing which is not something I want to do right now,(as long as she stays solid.)
