I had heard about that problem and hoped some of it was resolved as they iterated the design somewhat. OK with putting a little work into fitment, as I am intrigued and impressed with the simplicity and function of the part. Like the idea of eliminating the 'hinge' but not requiring removal of entire unit including mounts during some aspects of engine service.
Ireland Engineering stopped producing strut braces for E34 M5 and E34's. I surprisingly was able to find a NOS brace for an E34 non-M car, and am having the cross brace modified for the M5. I believe this vendor may have another, if anyone has an interest.
