Product review (4 stars): Hole spacing slightly different, but worked great.
My twenty-year old ceiling fan (no brand name) finally dropped a blade unexpectedly one day, so I ordered these replacement brackets.  The motor end of the brackets fit perfectly, but I had to mount the blade end using the center screw, then drill new holes for the bracket ends on either tip.  No worries as it took only about 30 minutes and my trusty ceiling fan was spinning smoothly again.  Thanks for saving me the time and expense of installing a replacement fan ... fixed it myself for under 20 bucks.  Two thumbs up!
