I checked mine just now and the upper and lower hinge brackets are .45 to .50 in spacing with the bottom also at .45”.
The bearings (upper and mid) are .436 wide with the lower being .50 inches.
Thus my lower would have a .05” spacing issue - if the brackets didn’t flex. Its a tight squeeze but it will go in. I suspect some variation in brackets forming.
Not a definite answer, but a reference point..
